4.75/5 stars 
 I absolutely loved the world-building in Heartless. It was so interesting to see how everything connected to Alice in Wonderland. I really enjoyed the buildup of Cath transforming into the Queen (even though I had hopes for a different ending (I LOVED JEST WAY TOO MUCH OKAY?)). Also the baking in this book makes me want to run into my kitchen and bake all the things (especially lemon tarts).
