Laura Dean Keeps Breaking Up with Me by Mariko Tamaki, illustrated by Rosemary Valero-O'Connell
This was a gift from a friend, and was a surprise hit for me. It's so heartfelt, and just so pleasant to look at — the art is beautiful. I loved that it was such a strangely optimistic break-up story, and how elegantly it put messy feelings into words and drawings.
