Witch Twins — Adele Griffin

Ten-year-olds Claire and Luna are identical twins--and witches.

Even though they can cast simple spells (with the supervision of their five-star-witch grandmother, Grandy) and know all sorts of magic, unfortunately no special charm can keep their divorced father from deciding to remarry. When he announces his engagement to Fluffy (her real name!), the girls panic, afraid he'll move away to Fluffy's native Texas. Claire and Luna throw the problem into the brewing vats, hoping to come up with a good, smart, tricky solution before the dreaded wedding.
