After Max's first adventure, you know that the mystery is based on something his great-great-ancestor, Jules Verne, discovered and kept secret.
This time Max and Alex start off rich, from the proceeds of their first adventure, but they quickly discover money can't buy health. At Basile's funeral, a homeless man with one droopy eye slips a cypher into their hands. There are signs Max's new friend Evie is sick, and his uncle, Verne, writes about a cure-all for just about anything.
Solving the cypher sets them on course for the cure, and while they're pursuing it, and the man with one droopy eye is pursuing them, Max learns his mother's cancer has come back.
If Max and Alex can find the cure first, who will they save? Max's mom or his friend Evie? Can he save them both?
I won't spoil the ending. You'll have to read to find out what happens.
A fun read!
