Olga Dies Dreaming

This started so well, with the story of two 40-something siblings of Puerto Rican descent living in New York living outwardly successful lives while continuing to reckon with the pain of their mother's abandonment when they were teens to pursue revolution catching me almost immediately with wit and well-drawn characters. It lets its storytelling fall by the wayside for a bit in the middle in favor of info dumps, but the ending was pretty strong.
