That ending.....umm I am still wondering about the possibilities of what has happen to Charlotte, where is she now????!!? I cannot wait for the next book. I cannot believe I have to wait until next year!! This book is truly unique and every different from all other YA books which is a huge relief. We meet many characters all with a different story both compelling and emotionally packed. ( There are some scenes that may make you want to tear up, just warning you) 
 I will start at the beginning. We meet Charlotte an orphaned high school girl who has suffer from strong compulsions to help other individuals which she names the Need. The compulsions are so strong that she has physical symptoms which only reside when she finally does what the Need wants. The Need gives her clues to where she is needed and visions seen the past and future of those she needs to help. You can say that Charlotte basically hypnotizes the person and guided by the Need tells them what they need to do to avoid drastic situations that puts their life at risk. Those who she helps immediately forget about her-thus the title the Forgotten for her kind. I felt her frustration and helplessness throughout the book once she realizes that once she completes her last Need she will truly be forgotten by all those she once new especially her adopted family and friends and she is suppose to burst into a bright light....literally guys(I know a bit dramatic, but its different which gains cool points) She tries to find ways out of this destiny and even turns to the enemy for help, fortunately she has help from unexpected characters to deal with her supposed ending.....
