Fantasy book with a Portal Potion Map

[Emma]

This is a bit of a different post. I saw a lady reading a book on the subway. It had a map in the front cover that said "The Portal Potion", which I assumed was the name of the book. The map had multiple fantasy worlds on it, Neverland and Wonderland are the only two I can remember, but there were probably 6 - 8 worlds. This is the only information about this book I have other than it also has a prologue and is a novel. I tried searching on Google, but unfortunately haven't been able to find the title.

When I googled "portal potion" this book popped up:

Beyond the Kingdoms

However, I don't see a map on the cover. This book was just published this month.

The description mentions Neverland and Wonderland.

Emma, is Beyond the Kingdoms the book you're looking for?
