Deadly assassins Allegra and Ace have been trying in vain to kill each other for years. With a mutual enemy threatening their mafias, they find themselves in an unexpected alliance, and soon discover killing each other isn't the only temptation they need to resist... ****** Allegra Grey is poised to be the next great American mafia leader, and she's more than living up to the name. A skilled assassin, there's only one target who's ever gotten away from her-suave, sinfully handsome Ace De Luca, heir to the Italian mafia and the Greys' biggest rival. When both mafias are faced with a dangerous threat, they're forced to work together to protect their families, and unexpected sparks fly. Allegra definitely isn't one to sleep with the enemy, especially an arrogant womanizer like Ace. But there's an undeniable electricity between them and Allegra's not sure it's all hatred. Ace may be bad news, but Allegra's never been afraid of a little danger. As the fire they're playing with grows to a scorching blaze, one thing is clear: trying to kill each other may have been difficult, but resisting this intense chemistry will be impossible.
