Book ~ "No Stone Unturned" (2019) Julie Moffett

From Goodreads ~ 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.

Lexi is a master hacker and director for X-Corp, an intelligence and security company. She recently got engaged to Slash, who is a government agent and fellow hacker.  Slash is lured to Italy because of something he did in his past.  He can't tell Lexi what it is as it's top secret.  Of course, she can't stay out of it so after hacking a bit, she heads to Italy to help him deal with whatever it is.  As Lexi and Slash travel across the country, they become involved with members in the Catholic church and discover that one of the priests may be Slash's father (he was found abandoned as a baby in a church).

Though this is the eleventh (and latest) in the Lexi Carmichael series, it works as a stand alone.  If you want to know the background, though, you should read the others.  I've like the series and have read them all.

It is written in first person perspective from Lexi's point of view and third person perspective from Slash and other's points of view.  I liked the writing style and there was humour.  In addition to the usual hacking, there was lots of adventure around Italy.  I missed the interaction she's had in the past with her best friends Basia, Elvis and Xavier (they were barely in the story).  It's been interesting to watch Lexi grow from being a geek with just one friend, no life and no social skills to not only having close friends, a fiancé with whom she is now living with, but also confidence.
