The Latch Key was  a brief but lovely story delivering into Elias (the Lord Sorcier of Half a Soul) as a father. We alternate between flashbacks of Elias' childhood with his malicious fairy father and Elias's current struggle with fatherhood. I was really drawn in to Elias' childhood. Olivia Atwater is great at invoking that fairytale vibe with trials, fairy logic,  and outsmarting evil monsters. 

I do wish there was a touch more of Elias relationship with his ward Abigail, but what we got was sweet. The ultimate message of learning to understand rather than domineering over your child was well received by me.
