Jaw breaker redesigned

I want to thank the manufacturer for changing the design of this shape to an easier to swallow elliptical shape instead of the jaw breaker shape.

GREAT READ
Format: Hardcover
I can’t stop thinking about Laws of Love and Logic, a debut novel by Debra Curtis. It’s beautifully written, incredibly heartbreaking, but nevertheless hopeful. It’s definitely not your typical romance novel rather it’s heavily character driven, and thought provoking. The characters feel so real. The way the author writes about the sisters’ relationship will stay with me forever. Also, having grown-up Catholic, I was so inspired to see progressive Catholicism with an emphasis on serving the most vulnerable, as being a foundational part of the sisters’ lives. The story spans decades, opening in the 70s and follows the characters into middle age. If you like books by Elizabeth Strout and Ann Patchett, you’ll love this one.
