The heart of 'It's Not Summer Without You' revolves around grief, love, and the messy process of growing up. It’s the second book in Jenny Han’s summer trilogy, and it digs deeper into Belly’s emotional rollercoaster after Conrad’s mom, Susannah, passes away. The theme of loss is so palpable—it’s not just about missing someone but also about how grief reshapes relationships. Belly’s torn between Conrad and Jeremiah, but it’s less about a love triangle and more about how love changes when you’re all hurting. The beach house, Cousins Beach, almost feels like another character, symbolizing the past they’re clinging to and the future they’re scared to face.
What really got me was how Han captures that weird in-between stage of life where you’re not a kid anymore but not quite an adult either. Belly’s trying to hold onto the magic of those childhood summers while everything around her is shifting. The book doesn’t offer easy answers, which makes it feel so real. That bittersweet ache of nostalgia? It’s everywhere—in the way Belly remembers Susannah, in the fractured bond between the Fisher boys, even in the salty air of Cousins. It’s a story about learning to let go, even when every part of you wants to freeze time.
