Published in 2007.
176 pages (according to amazon.com, as the pages are not numbered).
I picked up this book because I enjoyed Derek Kirk Kim's work in The Eternal Smile. I think it's a bit ambitious thematically for a 176-page graphic novel, but overall I enjoyed it a lot.
From the back cover:
Following a strange mishap on her 18th birthday, Grace Kwon is confronted with herself at three different periods in her life. The timing couldn't be worse as Grace and her friends desperately try to save a crumbling school play. Will her other selves wreak havoc on her present life or illuminate her uncertain future?
