The Rose Code by Kate Quinn

The Rose Code by Kate Quinn is a work of historical fiction that tells the story of three English female code breakers at Bletchley Park during World War II. 

The characters of Beth, Osla, and Mab are well-written by Quinn and cover a fascinating piece of history. The three women come from vastly different circumstances and are brought together at Bletchley Park in a story that involves heroism, tragedy, and a traitor that they must try to uncover. It's a long book, but an interesting tale set at a place critical to the war effort.

The Exchange by John Grisham

The Exchange by John Grisham is a highly entertaining novel that picks up the lives of Mitch and Abby McDeere fifteen years after The Firm by Grisham. 

In The Exchange, Mitch is a partner in a New York law firm and goes to Libya on a case he's assigned. When an associate from the firm gets kidnapped, the novel then goes into the attempts to get her released, with the large role played by Mitch and Abby. It's a fast-paced read and very enjoyable.
