Full review
This spoiler free Promise Me Sunshine by Cara Bastone review follows Lenny, a woman whose life has quietly fallen apart after the death of her best friend from cancer. Instead of going home to the apartment they shared, she drifts between temporary nanny jobs, rides the Staten Island Ferry all night, and does whatever she can to avoid sitting alone with her grief. When she meets Miles, the grumpy but surprisingly observant uncle of one of the kids she watches, he offers a strange bargain: he will help her work through the "live again" list her friend left behind if Lenny helps him show up better for his niece.
Most of the book lives in the small, everyday moments that come out of that deal. Miles walks Lenny through tiny, manageable steps toward living again, like eating regular meals, sleeping somewhere safe, and doing one thing from the list that is not about death. In return, Lenny nudges him into uncomfortable conversations with his family, forces him to see how much his niece actually needs him, and gradually becomes the person who understands the shape of his own losses. It is a slow burn in every sense, more about mutual caretaking and quiet jokes on late night trains than big speeches or dramatic declarations.
Because many readers will search for Promise Me Sunshine trigger warnings, it is worth saying clearly that the book sits very close to grief, cancer, anxiety and the exhaustion that comes with trying to function while you are barely holding it together. There are mentions of past illness, death of a best friend, complicated family dynamics and some panic spiral moments, but the story is written to feel ultimately comforting and hopeful rather than punishing. On the romance side, Promise Me Sunshine spice level and age rating land in the adult contemporary range, with one open door scene near the end that is more emotionally vulnerable and a bit awkward than graphic, and overall the tone fits mature older teens and adults who are comfortable with frank intimacy wrapped in heavy themes.
If you are wondering whether you need to read Ready or Not before Promise Me Sunshine, the short answer is no. They share an author, a New York vibe and an interest in characters who are doing real emotional work, but this is a standalone that makes full sense on its own. You can come to Lenny and Miles fresh and then go back to Ready or Not if you want more of Bastone’s mix of mutual pining, slow build trust and low drama conflict. If you are ready to see whether this grief filled but hopeful slow burn is for you, you can pick up Promise Me Sunshine on Amazon and then explore our contemporary romance collection for more healing centered love stories.

Grief, Trigger Warnings And Emotional Weight
Promise Me Sunshine spends a lot of time with grief, including the death of a best friend from cancer, complicated memories and the way mourning can derail work, housing and relationships.
There are references to illness, hospital stays, panic spirals, insomnia and characters who feel barely functional at times, though the narrative keeps its focus on coping and support rather than graphic details.
Readers who are especially sensitive to stories about cancer or recent loss may want to time this read carefully, but many will find comfort in how Bastone shows different, valid ways of grieving.
Key ideas
- Grief does not have a neat timeline and the people who help you most are often the ones willing to sit with the mess rather than rush you toward closure.
- Mutual caretaking, shared routines and small daily choices can be as romantic as grand gestures, especially when both characters are running on fumes.
- You can carry love for the person you lost and still choose a future where new relationships, new homes and new versions of yourself are possible.
