Wow I loved this! I started it last night and actually didn't want to put it down, but you know, sleep. Cal is such a believable character, and he experiences so much growth in this book! As does Leon, they grow together really. They complement each other so well.

The NASA and space aspects felt real, too, and the way social media was discussed was also an important part of the book. There are so many great discussions to be had here, and I loved every moment of it! This might be one I have to own.
