Bye Baby by Louise Collins

Donnie King.
Ruthless, sexy and assassin extraordinaire.
Or at least he used to be.
Now, Donnie’s washed up, drinking himself into unconsciousness night after night. He needs one more hit, one more chance to prove himself, to reclaim some dignity.
Enter Elliot Austin, the blue-eyed, blond.
An easy kill, or he should’ve been.
Donnie botches the hit and wakes up tied to a chair with a knife pressed to his jugular. He waits for Elliot to finish him off, but his young mark does something unexpected.
He kisses Donnie, then speaks over his shoulder as he leaves.
“Bye Baby.”
Humiliated, Donnie vows to end Elliot, but killing him is anything but easy.
He’s gifted at getting away, and is always one step ahead.
He teases, and humiliates, and drives Donnie crazy.
It’s an addicting game of cat and mouse that forces Donnie to climb out of the gutter, and get himself into shape.
Donnie wants Elliot dead, but he might just want him alive that little bit more.
But he’s not the only assassin after Elliot Austin…
