Mental Lady

James takes Remus, Sirius and Lily on a holiday and notices Sirius acting weird. Can he find out what is happening before the wrath takes Remus too? Will he lose his sanity on the way? Will Lily be able to save the odd group? When this is crossed with sherbet, an obsessive mushroom, an oddball owl, a flooded house, Voldymorto, a confused Dumbledore, a weird bunch of friends and a serious game of truth or dare, what will be the final result?
