"She asks for it every single nightโ€

I was skeptical about how personalized it would actually feel. Layla opened it and immediately pointed at the character and said "that's me!" The attention to detail in the illustration is incredible. The emotional intelligence theme came through every page naturally she didn't even realise she was learning.
