One of my many book boyfriends is Dimitri Belikov from The Vampire Academy Series and The Bloodlines Series by Richelle Mead. This review will contain spoilers.
Oh Dimitri...My second favorite guy from the Vampire Academy Series. He is everything a super hot hero dhampir should be. He is very loyal and brave and will do anything for Rose.
He starts out as Rose's trainer to catch her up on her training to be Lissa's bodyguard. They eventually fall in love. Dimitri saves Rose several times and then at the end of Shadow Kiss, Rose is faced with the fact her love has been turned into a Strigoi. Strigoi are super evil vampires that drink other vampires blood.
Be sure to carry around your holy water guys.... Just kidding...but just saying if you see a guy with really pale skin and red eyes. Get.the.crap.outta.there!
Anyway Rose and Dimitri have discussed before what would happen if one of them was turned. They decided they would rather die than be that monster. So at the end of Shadow Kiss Rose says she is off to kill the man she loves.
To this point is as far as I have gotten seeing as I have a ton of books to read and too little time. But in closing I wanna say he's hot. end of story
