An incredibly strong and memorable story.
Format: Hardcover, Format: Hardcover
⭐️⭐️⭐️⭐️⭐️ 5 glorious stars! Though she is big 656 paged girl, she offers so much heart. Lord how I loved this book. The characters were just so good together. Out of hardships, these women bound together for reasons of their own. Some of those reasons were tangled up with the other and none were wiser. Each, making an impact on another. This story offers hope where there’s tragedy, faith to persevere, lasting friendships, and love. Meg’s story of never giving up hope for her mother’s return, held me completely captive. 💖 Thank you Kathryn Stockett for penning a strong and memorable novel. Well done! I’m so pleased to have picked up this book to read and I hope you will too!

A book that hugs back.
Format: Hardcover, Format: Hardcover
I picked this book for my brother-in-law when we were celebrating my sister’s pregnancy, and the title ‘Why a daughter needs a dad’ sealed the deal. The illustrations are beautiful and full of tenderness. The messages on each page are simple and meaningful. I could so clearly picture him reading it to his baby girl someday. It’s the kind of book that isn’t just read – it’s felt. A thoughtful gift for someone you love – especially during such a special season of life.
