A wonderful, semi-spiritual fantasy novel set in an alternate universe version of (Victorian?) London where slavery was never abolished and the British Empire expands over nearly the entire planet. Two young Muslim teenagers accidentally come into contact with a supposedly extinct tyger (the spelling used in the book) who is revealed to be the mortal embodiment of a god who has been in conflict with another immortal deity across timelines and universes since providing humans with a "spark" of infinite power. The children must quickly learn to use their new found powers to save the tyger while, inspired by the demonic efforts of the other deity, London begins to burn and fall into mob rule around them.

An extremely timely read, and a beautiful telling of what can happen when you hone your powers of perception, imagination and creativity. This book longs for and deserves classroom discussion and to be written about in essays.

Positives for this middle grade book:
Sparks imagination in the reader
Black and white illustrations throughout are amazing
The length will be appealing to readers of this age.

Areas that didn't hit home for me:
The simplicity of the tyger at the beginning being in danger and able to hide
I like the concept and the obvious societal differences, but the characters didn't really grab me.
