Cipher - Aileen Erin Immature and boring. I didn't realize this was considered YA before I started reading or I wouldn't have bothered. The idea of helixes is interesting, but it ends up pretty convoluted with all the Ravens and the Seriglo or whatever. It became boring because it was needlessly complex and lacked the world-building needed to support it.

Keep in mind that I do not read YA, so this might actually be a great book compared to other YA. But if you compare it to adult UF or PNR? Well...
