This is a You've Got Mail retelling set in a very interesting fantasy world where there are demigods, zombies and talking animals who deliver mail. This is fun, cozy and entertaining. Both main characters go through internal conflicts, which makes the story more complex, and their relationship once they get together is so sweet. The side characters are all so lovable and they make the story more interesting to read. Lastly, there were a lot of different plotlines and I liked how they were tied together at the end.
