Tress of the Emerald Sea

This is possibly my favourite ever Sanderson book. I loved the whole thing with the spores and how Tress wasn't scared and so was able to learn so much more than anyone else about them. But mainly I just really loved the characters. I wasn't really an immense fan of Hoid before but his narrating made the story really lovely and funny. And his references to the rest of the Cosmere delighted me. 

But also just Tress and Charlie were both great as well as all the other crew members on the ship. I usually love all the characters in Sanderson books but this one especially has a collection of such amazing ones. It is like the ultimate feel-good book to me, especially the ending.
