This is probably a hand-made illustration - not a font (if you take a look at repeating letters, they are all different).
You may want to search the Dafont.com "handwritten" category for similar fonts:

or you may like one of the following similar fonts:
http://Scuffle free font by Rosie Tea [2014]
http://Sullivan by Magpie Paper Works [2011]

The title and authors names are hand written as all duplicate letters are different.

Sorry, I don't do "inspired by" matches well enough. Maybe someone else can help. (Edit: Perhaps Fivos).

Confirming it is hand-drawn. Adding to the list of substitutes Velik, Frosted and Icing.
