This book is a deeply personal and emotional story of one very special little girl and her determination to discover her true identity. Heidi has a strange life and no memories of her past. She is living with her severely disabled mum but has a lot of help from a neighbour Bernadette who has her own demons - she simply cannot leave her own apartment.
"We don't know exactly when my birthday is because I don't have a birth certificate, and Mama didn't know when her own birthday was, let alone mine. So we celebrated on February twelfth because as close as she could figure, I was about a week old on February nineteenth, which is when Bernadette found Mamma and me standing in the hallway outside her door."
So B. It will be enjoyed by a sensitive reader who takes time to walk with Heidi through her moving journey. You might like to read this review by Jen Robinson.
I recommend looking for The Illustrated Mum by Jacqueline Wilson if you enjoy So B. It. I also recommend The Honest truth as another book to read after So B. It.
