No Stone Unturned (Lexi Carmichael‪)‬

Geek girl Lexi Carmichael thought getting engaged would mean calmer days ahead. But when Slash's past brings up more questions than answers, she's not going to let anything—or anyone—drive them apart.

Getting engaged is supposed to be a fun, exciting time in a girl's life. But things are never that easy for Slash and me. Instead, someone is threatening to expose Slash's past—a past so secret, even I know very little about it.

Before I can get used the weight of Nonna's antique ring on my finger, he's on his way to Rome . . . and we're farther apart than we've ever been. Still, I have no intention of sitting at home and letting him take on the Vatican by himself.

With a little expert-level hacking, I learn Slash is keeping secrets from me. Big ones. Dangerous ones. In fact, the more I dig into Slash's past, the more I discover things about him I never knew—things that eventually pit us against each other.

From Rome to the Amalfi coast to the highest levels of the Vatican, we both race to discover the truth. No matter what I find, we're officially a team now, so I won't let him face this alone. Even if I don't know if our relationship can survive it.
