If There Be Thorns was better than Seeds of Yesterday. Seeds of Yesterday might have been my least favourite of the four books. If There Be Thorns had each chapter written in a different perspective, which i enjoyed, but i still had a hard time getting into the story. I found there was no climax in Seeds of Yesterday, which made it very hard to keep my attention. I kept waiting for something interesting to happen, but the story was very boring. Definitely not a young adult book.
