Crystal I have read three other books by Erin Kelly~The Dark Rose, The Ties That Bind and The Burning Air~and they are all fantastic! If you enjoyed The Poison Tree, I highly recommend checking out her other books as well. You won't be disappointed! Personally, The Dark Rose is my favorite by her thus far. Also, another recommendation I will make is Gillian Flynn. She's most popular for Gone Girl (which I didn't care for as a novel and thus didn't bother with the movie). However, her other two novels~Sharp Objects and Dark Places~are suburb reads! Hope this helps.
