Everything I Thought I Knew by Shannon Takaoka

Seventeen year old Chloe has had some bad luck - her heart failed. She has also had some great luck in the form of an organ donor just when she needed it. Ever since the heart transplant she feels differently and is living life more fully. She has secretly taken up surfing, parties a bit with a new set of friends and has a serious crush on her gorgeous surfing instructor. It is all in secret as is the strange dreams and feelings she keeps having that she can't explain. When Kai vanishes after she explains about her heart she needs answers. Could it be her new heart is reaching out to her in dreams or are they cellular memory? An interesting concept of science and the unexplained. For young adults but plenty of adults will enjoy this debut.  4 stars
