Is "achingly steady" a thing? If it's not, Promise Me Sunshine will be your introduction to that. A truly beautiful story, with characters you'll root for.
Miles is the backbone of this story, a constant force, a grumpy softie. Lenny, on the other hand, on surface-level, has some quirkiness to her, but is so much more - she's stronger than she thinks, even when grief takes her apart. She contains multitudes.
Everyone deals with grief differently, and it's always eye-opening to get insights about how others deal with it. Sometimes it's a life-long hum in the background, sometimes it comes out of nowhere and bashes you in the face, and sometimes it's a mix of the two. And while grief is the main theme of this story, it also has representations of different relationship dynamics, a reminder that life goes on, and that it's meant to be lived.
Promise Me Sunshine is equally devastating, healing, and swoony. From the very first page, this story grabbed my attention, and took me on a journey. Whatever I say will not do it justice, and is meant to be experienced by all of you.
