Book of Storms

Eleven-year-old Danny's parents are storm chasers - which sounds fun and exciting, and it is, so long as you aren't the son who has to wait behind at home. And one night, after a particularly fierce storm, Danny's parents don't come back. Stranger still, the old sycamore tree in Danny's yard seems to have been struck by lightning, and when he picks up a fragment of wood from the tree's heart, he finds he can hear voices... including that of the next door's rather uppity cat, Mitzy. The stick is a taro, a shard of lightning that bestows upon its bearer unnerving powers, including the ability to talk with plants and animals - and it is very valuable.
