The Al Dente Diet by Irene Bahrd

At his friend’s suggestion, and years of not cashing in his vacation time, Richard takes six weeks off to eat his way through Italy. In a comedy of errors, his flight is torture, he accidentally cancels his walking tour reservation, and has been hit on by nearly every woman he encounters after landing in Verona.
Italy isn’t what he thought it would be, until he meets an intriguing woman who shows zero interest, which only piques his.
Catarina isn’t your typical mafia princess, working as her family’s enforcer. Using the sweet American tourist as an alibi for a hit, he complicates her plans and is forced into her world. While their attraction is undeniable, Cat doesn’t do relationships, love, or anything resembling feelings. The last thing she needs is to be involved with a man who is leaving in six weeks. Determined to make the best of things, Richard manages to crack her hard exterior and finds himself eating more than Cat’s homemade pesto.
