Imagine the coolest New Year's Eve party ever. Set on the luxury yacht Aeon, just east of Tonga on the International Date Line. Celebrate the New Year, cruise across the dateline with a hangover, then do the whole damn thing again. Mac's idea was perfect and winning the lottery made it all the better, until Aeon is dragged a year into the past, instantly changing the future. Now Mac and everyone aboard must live the entire year again, trying desperately to get their lives back on track. Friendships will be strained to breaking point and lives will be lost as Mac tries to return Aeon to the dateline, single minded in his attempt to recreate the circumstance of the previous year and get his old life back. Mac's future is just a memory.
