The Magic Trap Book 5 by Jacqueline Davies

They practice, they study, and they practice some more. And who shows up? Their father, who has done such a good job of disappearing over the past few years.

Just as Evan and Jessie took on running a business in The Lemonade War and a court of law in The Lemonade Crime, in this fifth novel of the bestselling Lemonade War series, they take on the challenges of magic and illusion, all while discovering some hidden truths about their own family.
