Spellsinger, The Hour of the Gate, and The Day of the Dissonance

Three fantasy novels of music and magic in the beloved series by a #1 New York Times–bestselling author. A college slacker’s world is turned upside down when he’s transported to a new land where music can create magic. There, he teams up with other magical brethren and creates bonds of friendship he will honor for life.  Spellsinger: Jonathan Thomas Meriweather is a typical college student, interested in girls, music, and pot. But when an interdimensional portal lands him in another world, he learns that his musical ability can create magic, which he’ll need in order to stop a dark force.  The Hour of the Gate: Jon-Tom, whose posse now includes a wizarding turtle, a cowardly bat, and an otter with a filthy mind, must raise an army to fight the Plated Folk and end their queen’s plans to eat all the mammals in the land.  The Day of the Dissonance: Jon-Tom’s merry band went its separate ways after the battle of Jo-Troom Gate. But now the wizarding turtle, Clothahump, is dying, and Jon-Tom must embark on a new quest with his friends to search for a cure.
