The Vampire With the Dragon Tattoo (Love at Stake #14) by Kerrelyn Sparks

"Description"
He's Out of Control

Dougal Kincaid has something to prove. After being injured in a battle with the Malcontents, he's ready for active duty protecting unsuspecting mortals from these villainous vampires who want to rule the world. But first he has to get control of himself . . . because just the sight of a certain lovely doctor has his injured hand doing some peculiar things, not to mention the sizzling sensation that burns along his dragon tattoo.

Vampires? Vampires?! As a scientist, Leah is having trouble believing that these immortal creatures exist. But there they are, standing in front of her, asking for help in solving a genetic puzzle that can save mankind. There's even one in a sexy kilt! Just one look into Dougal's gorgeous green eyes sets her pulse racing. But can she trust him—and the overwhelming desire that refuses to be ignored?
"Review"
“It had replayed in her mind, over and over, growing in importance till it seemed her whole life could be slotted into two categories. Life before the kiss, and life after the kiss. Her life before the kiss had moved step by step ever closer to the predestined event. Meeting Dougal. And kissing him.”
― Kerrelyn Sparks, The Vampire With the Dragon Tattoo 

Love at Stake is one of my most favourite paranormal series and I have read and loved all the books. this one was no exception. A perfect mix of humour, romance, action and suspense.
Dougal has waited for three hundred years for his love to find him and now finally she is here but she is scared of him and think that he is a monster, a vampire, although at some level she does recognise him but can she get over the fact that he is "dead" half of the time.....
Leah is helping the vamps to fight evil and defeat the viscous vampires, including master Han. Dougal's mission is to protect her as well as defeat evil vamps and they must go to China, a place he never wanted to revisit, place where he lost his true love, Lei, three hundred years ago and where he might lose Leah as well. He vowed that he will not fail her and will protect her at any cost but can he fulfil it.....
When Leah was taken by the enemy he feels his entire world falling apart but in the end evil is defeated and they are reunited.
I love happy endings!! This book has the happiest one :)
