Hi, can you write me a synopsis for a fantasy book full of dark humor whose main characters are four unlikely friends: a demon hunter, a vampire baroness, a werewolf and a gravedigger. They form a team for special tasks and occasionally save the world.

John, a demon hunter who likes to play ball with demons heads, needs to find a way to rescue his brother who fell into another dimention. With the help of a vampire baroness called Gruba, a werewolf and a gravedigger, they would put their friendship to the test and brotherhood to the limits while casting spells that would take them to all sorts of psychodelic scenarios.
