I really liked Breadcrumbs. There was something very magical and enchanting about the book, and the first half of the book had a lot of references to Narnia and Hogwarts that I just loved. 
 The ending felt a little rushed and ended more abruptly than I thought it would. Quite honestly, I expected something a little better, especially since it was obvious that Ursu put a lot of thought into the rest of the book. Ending aside, it was enjoyable, and I loved seeing Hazel's quirks, insecurities, and her sense of wonder and awe. It really is a lovely story of growing up and growing apart from friends. 
 I loved Hazel, who is a very imaginative, smart girl who doesn't fit in. There was a certain innocence about her, and while she had to step out of the fairy-tale world she loves to save Jack, I hope it's something she doesn't lose. 
 It gets a 4 out of 5. I really liked it, and there's certainly something very enchanting and lovely about this book.
