Practical Magic 2 by Alice Hoffman

The family's story began in 1620, when Maria Owens was tried for witchcraft, and every Owens descendant was cursed in love. Now, in Cambridge, seventy-eight-year-old Jet Owens hears the deathwatch beetle and knows she has only seven days to live. Before she goes, she discovers The Book of the Raven, a dangerous magical grimoire that may hold the secret to breaking the curse once and for all. 

Her sister Franny, nieces Sally and Gillian, and the next Owens generation--Antonia and Kylie--must face the truth of their legacy. When Kylie's boyfriend falls into a coma after they confess their love, she flees to Europe in search of answers, embracing perilous left-handed magic that could destroy everything the Owens clan has fought to protect.

Spanning from New York City to Europe, Practical Magic 2 weaves a spellbinding tale of Owens family witches, sacrifice, and survival. A breathtaking and masterful conclusion to the beloved series, it brings together three generations of Owens women--and one long-lost brother--for a dazzling finale that proves the only cure for love is to love more.
