"Tempted" by Lori Foster

This is a compilation of three stories previously published by the author.  The main character in each is one of a trio of siblings, two brothers and their younger sister.  The book is a contemporary romance, so each story is about the siblings falling in love.  I used to like Foster's writing but as I've read other authors I've come to realize that her character development is rather weak and her stories are not very believable.  521 pages.
