Cross My Heart and Hope To Die by James Patterson are two parts of one story. The first part takes place in Cross My Heart and it concludes in Hope To Die. To my knowledge, this was the first time James Patterson did this so, naturally, many fans were upset with the cliffhanger ending of the first book. I wasn’t because I knew this going in. If anything, it made me look forward to reading Hope To Die even more, so I could see how things wrapped up.
