Worth the Trouble - Simply Trouble Series, #3

Book Three in the Simply Trouble Series Carlo Moretti, an Italian intelligence operative, is very good at his job. But when the latest operation goes sideways, putting his CIA counterpart's sister in danger; Carlo is asked to look after the woman. Babysitting is sometimes part of the job, so for Carlo, this is just another Thursday. Doctor Alessandra Salvatore doesn't need a babysitter, nor does she have time to rearrange her life because her brother thinks she 'might' be in danger.
And she definitely doesn't need the electrifying neurological reaction she has when she comes face to face with the Roman gladiator of a man sent to guard her. Carlo and Alessandra have both worked tirelessly in their chosen professions, and neither has room for a relationship, no matter how undeniable the chaotic attraction. From the terracotta rooftops of Rome to the remote jungles of South America, the two are thrust into a world of intrigue and sexual tension.
Can they build something together or is it better to let the passion fizzle out and amicably part ways?
