Zombie wedding crashers

"After Regan, Sofia, Bennett, and Darius successfully banished the witch's curse that led their science teacher to try to clone them, their lives should be back to normal, right? Not so! Because the curse is back and stronger than ever. Sofia's dad and Bennett's mom are finally getting married, and nothing could possibly ruin such a beautiful day . . . except for a horde of the rambling, brain-hungry undead!"--Amazon.
