She’s a Spitfire by Chloe Liese

One fiery-haired, sexy scientist finds her perfect complement in a dark and handsome soccer star. Opposites attract, and they’ve got chemistry that’s explosive—literally.
Physics calls it entropy. Philosophy calls it Murphy’s Law: If something can go wrong, eventually it will. Professionally and personally speaking, Zed’s familiar with the principle. After a decade of trying to alter the atomic makeup of the mafia from its nucleus, now he’s set on leaving The Life and pursuing his heart. Problem is, the sassy, hot-headed spitfire he can’t quit is meddling in his slow burn escape plan, and turning it into full-on combustion.
Not to mention, Nairne’s got a painful history she won’t talk about and more secrets than she has lab instruments—which is really saying something. In an ideal world, the bad boy footballer would follow the brainy beauty overseas and they’d live happily ever after. But Murphy’s Law is proven true, as Zed finds his world imploding and his escape plan foiled. These enemies turned lovers end up discovering how costly it can be to meet the right person at the wrong time.
A present he can’t escape.
A past she can’t forget.
A future they won’t stop fighting for.
They say all’s fair in love…and war.
