Juliya is a half-elf who has escaped the slums of Felbreach to seek a better life for herself. In pursuit of this, she steals a scroll for a client that promised her a generous reward. Instead he betrays her and leaves her to die in the room she rented in Barnhal. She is revived by a local cleric that reveals to her the dangers of the scroll she has given to her client turned enemy, Frost Dirvent. Now she and a group of adventurers have to track down Frost before he can bring about a new apocalypse.
If that description sounds like it could be the hook for one of your D&d campaigns, that is not by accident. I have no doubt that Matthew Cesca is an experiences Dungeon Master, and that his trilogy is largely based on a game he ran for his friends. This fact is both the book's greatest strength and most glaring weakness.
Primarily, this means that anyone who plays D&d, or any ttrpg, can easily place themselves and their fellow party mates in the shoes of Juliya, Braylen, Braddock and the rest of their companions. The world Cesca has laid out for you in this book is one that, if he had a mind to, would make a good source book for a campaign setting. I suspect that the D&d community, myself included, will hold this book as a success of their community and as an example of what good Dungeon Masters can aspire to.
This book is not without its weak points. The greatest of them is that, since these were characters likely thought of by players, they read more like archetypes than they do real people at several different intersections in the book. The cleric is deeply religious, but there isn't a big revelation about how his relationship with his god has informed how he lives his life. Instead, he became a cleric because of a story he found particularly moving as a child.
Juilya herself has all of the mistrust and independent streaks you would expect of a player who wanted to play a rogue without much consideration as to what someone's life would be like if they had to fight for each day of survival. Her struggles with her racial identity seem to be more of a set-piece rather than a deeply personal insight in to what her culture is like.
This is only the first of three books, and I hope these characters get the chance to show more of their individuality as I read through the other two. The world is interesting, and I would very much like to take may players through it if I ever get the chance, but the characters the story focuses on don't pull me in the way I wish they would.
