One for the Money by Nicole S. Goodin

Tyler
I’m no stranger to rival hackers, but I swear if I’m outdone by Armageddon again, it’ll be over my dead body. This war has gone on too long, and I’m going to beat him if it’s the last thing I do.
The only thing that could steal my focus is her.
Amarah Garcia. One look at those long legs and dark eyes and I’m totally done for. One date and I’m completely hooked.

Amarah
You don’t expect Mr. Right to turn up on your doorstep, but that’s exactly where he was… only Tyler Watson is not the man I should be letting into my life. In fact, he’s the furthest thing from it.
I thought I could play the game – play him, but the only thing I’m doing is playing myself.
Falling for the enemy was never part of my plan, but now I’m in so deep I don’t know which way is up.
The secret I’m keeping threatens to break us, but will he find out the truth?
