Gemina

Illuminae completely blew my mind, but Gemina was just a good read. I liked Hanna and Nik separately but didn't buy them as a couple in love. And I didn't think the plot was as strong as Illuminae either until the very end (when the title started to make sense). At times it felt like a video game with the cartoonish bad guys being X'd out a few at a time. Still loved the unique presentation and formatting (don't read this on your phone!) Here's hoping that the trilogy will end on a strong note.
