SORCERER OF SMALL MAGIC.

I loved this! If Carry On and Boyfriend Material had a love child, this would be it - though this should not misguide you - this is not a romance heavy book AT ALL. Instead it focuses a lot on character development and world building.
And this author knows how to pull off a whimsical writing style which completely caught me and didn't let me put the book down.
I need to be reunited with Grimm and Leo ASAP! Cannot wait for the next one!
