5 ANGELS: "Tank is fighting for control of the Lady Blue with his mate Zachary at his side when it's pulled into an uncharted wormhole. Zachary is injured, needing help from their resident doctor, Imlay before they realize that there fuel cells are almost empty. Things between Tank and Zachary, or Tweak as he's called, are strained because for some unknown reason Tweak won't let Tank claim him. Tweak explains that on his world they have a formal ritual to truly bond before they can mate. Tank will do anything for Tweak but it isn't going to be easy to control his feelings. After a mishap on a planet whose inhabitants are determined to capture them, they crash land on what they soon learn is ancient Earth, where they hope to repair their ship and find fuel. While in search of fuel, they run into a new friend, Mo, who claims to be a computer genius. But can anyone form such a backward culture help them? Will Tank find a way back to the future so he can claim his mate? Can the Lady Blue survive the trials ahead? Tank's Tweak is a fast-paced, action-filled story that held me riveted from the start. There is much scientific discussion about what would happen if someone encountered a wormhole and it was fascinating to experience it as the crew lived through the harrowing event. Tank couldn't understand why Tweak wouldn't allow him to claim him, but once he understood, it was wonderful to see how he was willing to move heaven and earth to please his man. It was funny how Tweak's mother was just as unusual and fierce as Tank described her, keeping Tank on his best behavior. Tweak's love for his mother was as beautiful and strong as hers was for him. I can't imagine how I would react if I stumbled upon a craft from the future, but Mo seemed to adapt without problems. There is never a dull moment in the lives of the Lady Blue Crew." -- Teresa, Fallen Angel Reviews

"I really adored this fifth book and it was all due, mainly, to Zackary! Of course, the authors have also managed to keep the fun in these books without them becoming staid. Zackary is a Paxtillian and he loves his mom and his mom's fruitcake more than anything in the world. Until he meets Tank. Zackary knows that Tank is his mate but he can't do anything about it. His mom has drilled the mating ritual into his head since birth and no intercourse is allowed until the ritual is complete. Tank is a little frustrated. He is climbing out of his skin to claim Zackary and doesn't understand why that can't happen. He is in love with his mate and his quirky ways and just wants to take care of him and protect him forever. Protecting everyone on the Lady Blue might be a little difficult when the ship gets sucked through a wormhole trying to outrun the Elite Forces. The wormhole sends them to Old Earth - centuries in the past! Figuring out how to get back to their time and get Zackary to Paxtil for the ritual makes for a lot of laughs!" -- Christy Duke, Rainbow Book Reviews

“We got ten minutes. What can you do in ten minutes?”

Tank’s eyebrow arched for just a second, and then the man grinned. “Drop your pants, and I’ll show you.”

Zackary couldn’t scramble off of Tank’s lap fast enough. He unbuttoned his pants and pushed them off his legs, thankful that he had forgotten his shoes that day. When he looked back up at Tank, he nearly swallowed his tongue.


Tank had pushed his pants down his thighs. He was sitting back in his seat slowly stroking his cock as he watched Zackary. The hunger in Tank’s eyes made Zackary’s knees shake. He felt like he was being eaten alive.


Zackary bit his bottom lip as he stared up at his mate from under his lashes. His cock was hard and throbbing as it jutted from between his legs. He had only done this once, but Zackary was addicted to sex with Tank now.

He wanted more.

Zackary leaned forward and lapped at his mate’s cock before grinning up at him. “You always taste so good.”

“Get your sexy ass up here, tweak.” Tank growled low, his voice slightly hoarse.

“I am sexy, aren’t I?”

Tank chuckled as he held his cock, stroking it a few more times. “Fishing for compliments, are you?”

Zackary shook his head. “I’m not fishing. I’m outright asking.” He grinned as climbed up on Tank’s lap. He placed his hands on Tank’s shoulders, slowly lowered his body, letting his ass nudge his mate’s cock.

“I need to stretch you first, tweak.” Tank groaned as his pecs jerked.

Zackary leaned forward and ran his tongue over one of Tank’s large pecs and then sucked in his dark brown nipple. Tank’s salty skin sent Zackary’s senses reeling. He parted his lips, teasing Tank’s nipple with his teeth. His mate groaned, pushing his hips higher as his hand ran down the crease in Zackary’s backside, his large finger tapping at Zackary’s hole.

Zackary’s ass pulsed to be filled. He moaned around Tank’s nipple, his hands exploring his mate’s massive chest as he tried to snap his hips and impale himself on Tank’s sausage-like finger.

“Sit up, tweak,” Tank panted.

Zackary raised his ass higher, sticking his ass out like an animal in heat. And he was in heat. He groaned when the movement brought his cock into full contact with Tank’s tight, muscular abdomen, giving him the pleasure of flaming hot friction.

“Fuck me,” he begged.

“I plan on it,” Tank whispered as he lined his cock up. “Tell me if you can’t handle this.”

Zackary nodded as he slowly lowered his body onto Tank’s large shaft. The burn almost made him stop as the head of Tank’s cock breached him. Zackary stopped, took a few deep breaths, and then started to lower himself little by little.

“Oh fuck, tweak.” Tank’s head fell back as his lips parted.

Zackary loved the fact that he could make his mate fall to pieces right underneath him. It was a gratifying feeling that Zackary cherished. He exhaled loudly when he finally bottomed out, his ass resting on Tank’s balls. He reached up, entwining his arms around Tank’s neck as he waited for the burn to ease. Zackary would endure the burn because he knew what was soon to follow.

“T–tell me when, tweak,” Tank said in a strained voice.

Zackary lifted his ass a fraction, testing to see if he could handle any movement. He groaned when Tank’s cock slid over his prostate. Damn if that wasn’t a glorious feeling. “I’m ready.”

Tank growled as he grabbed Zackary’s sides and thrust his hips high into the air, almost sending Zackary flying. Zackary laughed as Tank did it again, and then again. “If you knock me off of your lap, I’m gonna be real pissed.”

Tank chuckled as he snapped his hips repeatedly. Zackary forgot about his threat as Tank sent his mind skyrocketing. Zackary caught on and began to bounce onto Tank’s cock. He leaned forward and bit one of Tank’s nipples, teasing it with his tongue.

“That’s it, tweak. Ride me, baby,” Tank encouraged as Zackary planted his feet on either side of Tank’s hips and took over. Lightning strikes struck throughout his body as Zackary rode his massive lion.

“C–close,” Zackary warned as his balls ground between them.

“Then come for me, love.”
