House of Bone and Rain

"For childhood friends Gabe, Xavier, Tavo, Paul, and Bimbo, death has always been close. Hurricanes. Car accidents. Gang violence. Suicide. 'Estamos rodeados de fantasmas' was Gabe's grandmother's refrain: 'We are surrounded by ghosts.' But this time is different. Bimbo's mom has been shot dead. Feral with grief, Bimbo has become unrecognizable, taking no prisoners in his search for names. Soon they learn Maria was gunned down by guys working for the drug kingpin of Puerto Rico. No one has ever gone up against him and survived"
