SOLVED. Newer YA book about switching places [s]

[Sheri]

I overheard someone talking about this fairly new YA fiction book that involves two girls who switch places everyday at the same time. It had a time in the title like 4:39 or something like that.

[Jessica (Goldenfurpro)]

3:59?

[Kate]

Sheri, Is this the book? We like to have it confirmed before we shelve the book and consider it solved.

[Lobstergirl, au gratin]

Sheri is no longer in the group, but she did shelve Jessica's suggested book on 2/19 and read it on 4/10. We can probably consider this solved.
