What does it mean to be a big brother? Ace was once the smallest one in the house. His gentle big sister, Bailey, taught him how to wait, watch, protect, make room, stay calm, and notice when someone needed help. But when Bailey went home to a place Ace could not follow, the house felt different. Ace missed the one who always knew what to do. Then Prince arrived. Prince was tiny, white, fast, and full of energy-a little puppy who moved like a storm and did not yet know where his paws belonged. At first, Ace was not sure he wanted a little brother. But Prince needed someone to show him the rules, help him feel safe, and make room for him in the family. As Ace remembers Bailey's lessons, he begins to understand something important: Big brothers notice. Big Brother Ace: A True Story About Learning to Lead with Love is a tender picture book about love, loss, change, emotional resilience, and becoming the kind of big brother someone else needs. Through Ace's journey from sadness to pride, young readers discover that the love we receive can become the love we share. Perfect for children ages 4-8, pet-loving families, children becoming older siblings, and anyone adjusting to a new family shape. Written and illustrated by Ronald P. McGuire.
