Upgrade by Blake Crouch
Like Andy Weir (Project Hail Mary, The Martian), Blake Crouch writes sci-fi that’s intellectually stimulating thanks to the science involved, but at the same time, real page-turners. (I think I read Upgrade in two days, total.) That said, Upgrade may have been too much of a page-turner; it felt perfunctory given the heady topic involved (genetic engineering). As for the ending, I get why Crouch wanted to end the novel on an optimistic note, but it rang a bit false and left a bad taste in my mouth.
