At Any Given Time — L. Darby Gibbs

Though Sam's been claiming that teamwork is a pain in the neck, she really wasn't looking for proof.

When time traveler Samantha Gorz finds herself stuck in a 17-century Sicilian catacomb filled with preserved friars and other important citizens, she must extend her stay masquerading as a Capuchin brother.

Helping the search and retrieval team narrow down where she is in time was a piece of cake compared to dealing with a stalker who thinks she's horning in on his territory, her custom-engineered lizard companion's sulky behavior and the S&R jumper who decided to try out his new prototype for her rescue.

It was just your general, run of the mill visit to a catacomb.
