Handle Me by Kira Sinclair

Savannah "Van" Cantrell is the girl Ty Colson could never have. She's also the sister of his best friend–and blames Ty for his death in Afghanistan. The last thing Ty needs is a reunion with Van. Or a reminder of their too–potent chemistry. 

Van wants to give her brother's dog a loving home, but seeing Ty means facing the anger, the blame and the electric current of sexual energy between them. And while Van trusts him to handle almost anything–including her body against his–she'll never trust her heart to a man determined to walk back into the line of fire.
