“This is a masterful and fun read.” – Sandy Wasserman, The Sydney Taylor Shmooze

What do you get when you combine a cardboard box, some spare parts, and a smartphone?

A time machine, of course!

Max likes to build things from cardboard, and a time machine is his latest invention. However, he's not so good at building friendships. That's why he's been avoiding Emma, the new girl in class.

When they learn that three angels once visited the biblical Abraham and Sarah, Max and Emma are both bursting with questions. Did the angels have wings? What did they eat? There's only one way for Max to find out: travel back in time to meet Abraham, Sarah, and the angels himself.

He might even learn something about friendship along the way.
