I was in the middle of typing a long review and I lost it. The book is just OK when the author lets go of the conceit of including found vintage photographs. The photos range from stunning to creepy to out of place. They are never worked into the story well. Usually the author says, "And then so and so found a photo of x" and then it shows the photo. It's really disappointing as the idea of using photos is what drew me to the book in the first place.
very X-Men. Time traveling, teenage X-Men. I didn't have as much problem with that as other reviewers, but it is very different than what's advertised.
The end was very unsatisfactorily left open for a sequel. I probably won't be reading it
