In the Shadow of Vesuvius by Tasha Alexander

The book opens with a body. Emily and her husband Colin have traveled to Pompeii with their friend Ivy and they are the ones to discover that one of the bodes is from rather more recent times than nearly 1800 years ago. Their friend Jeremy also shows up as does someone from Colin's past, someone who will change the course of Emily's life.
Regular readers of the series will probably enjoy the book; we get alternating stories between Emily and a woman from before Vesuvius erupted. We also have the normal sort of mystery that you would expect from a Lady Emily story though the surprise that changes Emily's life will definitely be a sticking point for some readers (as it was for me.)
