Dragonfly In Amber by Diana Gabaldon

This is an excellent time-travel romance.  The second in the Outlander series.  I enjoyed it just as much as the first book.  There are references to the first book "Outlander" but not so much to be overdone.  I love reading series books in order and I can't wait for to read the 3rd in this series.

It's now 1968, and Claire Beauchamp Randall has returned to Inverness, Scotland, with her daughter, Brianna.

This is Claire's first visit back since she and husband Frank visited 22 years before--when she walked through a Druid stone circle into the middle of the 18th century. Now, Frank is dead, and Claire hopes to learn what happened to the second great love of her life--gallant Jamie Fraser, laird of Lallybroch whom she married during her journey into the past.

She's also looking for a way to tell Brianna who her real father is. Framed by these dilemmas, the bulk of the story consists of the second installment of Claire and Jamie's adventures. Escaping the English death sentence passed against Jamie, they flee to prerevolutionary Paris, where they secretly work at foiling Bonnie Prince Charlie's efforts to regain the Scottish throne.
