Her Last Holiday by C L Taylor

I read this a while ago and had to refresh my mind as to the story. Fran's sister Jenna disappears on what was going to be an idyllic retreat and was never heard or seen again. Now the man who owns and ran the retreat is out of prison but will not disclose what happened to the third victim at the retreat - Fran's sister. Fran wants to discover what happened to Jenna, and books herself for the retreat coming face to face with whom she considers her sister's murderer. Is Fran putting herself into too much danger because there are secrets that people would like to stay buried with Jenna. Told in two separate time lines - when Jenna was alive and the present the suspense is quite electric. A well written thriller. Sent by Avon Books UK for an unbiased review, courtesy of Netgalley.
