Reading 'It's Not Summer Without You' was an emotional rollercoaster, especially with how the story handles loss and grief. The character who dies is Conrad and Jeremiah's mother, Susannah Fisher. Her death isn't just a plot point—it's the heart of the story, shaping everything the boys and Belly go through. Susannah’s battle with cancer is mentioned throughout the book, but her actual death happens before the events of this sequel, casting a long shadow over everyone. The way Jenny Han writes about grief is so raw and real. You feel Conrad’s anger, Jeremiah’s attempts to stay strong, and Belly’s confusion as she navigates her feelings for both brothers while mourning someone who was like a second mother to her.
What makes Susannah’s death hit harder is how present she still feels. Flashbacks and memories keep her alive in the characters’ minds, especially during their summer at Cousins Beach. The house itself feels haunted by her absence, and every interaction between the characters is tinged with what they’ve lost. Conrad’s spiral into depression, Jeremiah’s reckless behavior, and even Belly’s conflicted emotions all tie back to Susannah. The book doesn’t just focus on the sadness, though—it shows how grief can push people apart or pull them together, sometimes both at once. The way Han explores these relationships makes the loss feel even more personal, like you’re mourning alongside them.
