I'm having a really good reading year as well. There have been some weird and wonderful contenders, but my top 5 so far are:
The Hero of this Story, by Elizabeth McCracken.
Trespasses, by Louise Kennedy.
Signal Fires, by Dani Shapiro.
Romantic Comedy, by Curtis Sittenfeld.
Wedding Toasts I'll Never Give, by Ada Calhoun.
My recent crop:
23. Quietly Hostile, by Samantha Irby. Her latest book of essays. I didn't love every chapter of this, but the ones I did, I really did. Particular highlights were her essay about how to respond when people are saying awful things about what you like or have done, and "The Last Normal Day" which I found hilarious, despite lockdown being a very sore spot for me. Several others made me laugh out loud. Probably not a bold, but definitely worth the time.
24. Wedding Toasts I'll Never Give, by Ada Calhoun. In my top 5! Short, fabulous, and endlessly quotable book of essays about marriage. Highly recommended for anyone who is married, was married, or is getting married.
25. The Summer Tree, Guy Gavriel Kay. First of a high fantasy trilogy that I loved as a teenager. They haven't aged particularly well, but are still a classic of the genre. I can forgive the mannered style and some dubious plotlines just because they're so familiar to me, but I doubt I'd feel the same way if I was reading this for the first time as an adult.
26. Dear Genius: The Letters of Ursula Nordstrom. Ursula Nordstrom was Director of the Department of Books for Boys and Girls at Harper from 1940 to 1973, during which time she published E.B. White, Maurice Sendak, Shel Silverstein and other leading lights of children's literature. As well as being a published author herself, she wrote fabulous letters to her authors, and this collection is a joy. If you're interested in publishing, classic children's literature, or just fabulous New York broads, this is worth a read.
