This is dangerous because of how easy it is to say lashon hara. So I will hold myself back and only mention great, great books.
The new Avner Gold books are a breath of fresh air. Great reading, plot development, character development. I want to go back to The Promised Child and start reading them all over again. They’re a fun, adventurous ride too.
Meir Uri Gottesman has some magnificent books. I would say the same about his books too. There’s a new one, I don’t know the title, The Harp, Deep Blue and others. If you’re into a charming little read, try his Chaimkel the Dreamer (and R’ Charles Wengrov’s book, Zalman’s Menorah. Speaking of charming little reads, The Rabbi of 84th Street, by Warren Kosak [a secular but deeply sympathetic journalist] about Rav Chazkel Besser is agood read.)
Speaking of bios, there are some wonderful ones. In Every Generation, about the Yudelevitch family; My Footsteps Echo, about a 19th century meshulach; Greatness in Our Midst, about Rav Simcha Wasserman; many of the Artscroll bios, like Rav Pam’s.
And one more fiction before I have to run: Oh, I forgot the title. Sun inside Rain? by M. Bassara, Feldheim, very different and you will want to read this before your kids if that is how you handle things.
