Here a synopsis from Kerry's website:
Zoë loves Henry. Henry dumps Zoë. Zoë wants Henry back - at any cost. Zoë's two best friends come up with a plan to help Zoë get what she thinks she wants. The plan: make Henry jealous. But the plan takes a surprising turn... Spanning thirty-one days in the cycle of a breakup, Kerry Cohen Hoffmann's funny and touching novel depicts a girl whose single-minded focus on her ex-boyfriend has pulled her far from the person she most needs to win back - herself.
It comes out in June! Eeee! :)
