Vikram by Isadora Hart

Cassie hasn’t been off the ship a minute when her boss is assassinated and she’s looking into the barrel of a gun.
Now lead negotiator at the biggest conference in her charity’s history and sure she’s in mortal danger, Cassie is completely out of her depth.
Vikram should be the answer to all her problems: A big, strong bodyguard with one of the most prestigious security companies in the universe.
And then she fell head over heels for him.

Vikram has wanted to be a bodyguard his whole life. He spent two extra years at the training academy learning to control the rages every Suytovian is burdened with.
One look at Cassie and all that training unravels.
With his job and Cassie’s life on the line, Vikram’s blood feels like it’s on fire twenty-four-seven, and his control is unraveling minute by minute. If he’s not careful, he’ll lose both before the conference is over.
