I probably shouldn’t have expected much from a book that drew cover comparisons to The Hunger Games (which I hated) and The Maze Runner (which looks boring to me).
The narrator of the book somehow managed to weave a web of lies and deceit, despite making no active decisions until the second half of the book. Much of the plot required more suspension of belief than should be expected, and despite the title, there are few aspects of the original tale of Icarus beyond shallow, almost cosmetic references.
If you absolutely want to read more of the exhausted YA dystopian genre, this is probably a good book to check out, but otherwise, Children of Icarus offers nothing new or interesting for the subgenre.
