Looking for books about late bloomers.

(Tldr at the end) I’m in my late 20s and I’ve been dealing with chronic illness for the past decade or so, so I’ve missed out on a lot of the typical young adult life. I’ve missed most of the milestones you’re supposed to hit in your 20s and I feel so far behind all of my peers. I’m starting to feel like I’m so far behind that there’s just no way I can catch up – like I’ve missed the window to build the foundations of my life experience and now that’s it, I missed the train. I’m sick of reading coming of age stories about people in their 20s having adventures that I know I’ll never have.

So I want to read about people whose lives didn’t really start until much later in their life than usual. I want to read about late bloomers, whatever that means to you. Fiction or nonfiction (especially memoirs) are both great.

TLDR: I lost my 20s to chronic illness and now I’m looking for fiction or nonfiction books about late bloomers who still had interesting lives even if they got started really late.
