This was really cute! The ending "twist" was a little bit predictable, though there's certainly a case to be made for happily ever after, and I liked basically everything else about this book: boy-girl twins, dual POV (if done right - which this was), serious but non-stigmatized discussion of mental health, family bonds (both Louis & Willa and Frances & Arrow), soft romance, and a little bit magic. Obviously, this book had all that and more, and I enjoyed it very much.
