The Book of Magic: Alice Hoffman

For centuries, the Owens family has been cursed in matters of love. When beloved aunt Jet Owens hears the sound of the deathwatch beetle, she knows that it is a signal. She has finally discovered the secret to breaking the curse, but time is running out. She has only seven days to live.

Unaware of the family's witchcraft lineage and all it entails, one of the young sisters of the new Owens generation has fallen in love. As the curse strikes once again, her love's fate hangs in the balance, spurring three generations of Owens to venture back to where it all began and use their gifts to break the spell that has marked all their lives.

But doing so threatens to destroy everything the family has fought so hard to protect. How much will they give up for the greatest gift of all?
