People have always told stories about the house at the end of Calle Sol. They say it belongs to a mad scientist whose wife cursed it. They say a green-skinned witch girl lives there. People throw wishes written on paper over the wall around the house, hoping that the witch will grant them. But no one ever goes there, so no one really knows what’s going on. In A Fierce and Subtle Poison, by Samantha Mabry, protagonist Lucas will get closer to figuring out the house’s mysteries than anyone.
Lucas lives a charmed life in San Juan, Puerto Rico. His father is a rich white developer and Lucas has never had to work. Every summer, he lives in his father’s hotel and lives it up with his three friends, drinking and trying to get into girls’ shorts. He’s spoiled, but at least he knows it. He tries not to be too much of a gringo. He’s always been curious about the house at the end of Calle Sol and, the summer he turns 17, he actually makes contact with someone who lives in the house. One night, Marisol, the girl Lucas is trying to hook up with, makes a wish and throws it over the wall. The next day, she disappears and a note appears in Lucas’s hotel room telling him that Marisol’s wish can’t be granted.
Over the next several weeks, Lucas will end up in the middle of a mystery involving missing girls, the aforementioned mad scientist, and a girl who poisons everything she comes in contact with. This is not a metaphor. The first time Lucas meets Isabel, she demonstrates her condition by blowing on a wasp and killing it in midair.
Isabel ends up being the most interesting character in A Fierce and Subtle Poison, followed closely by her father, Dr. Ford. Dr Ford fits it in nicely to the rich tradition of crazed scientists who are willing to do anything to achieve their goals. Isabel is something special, though. Her condition (for lack of a better word) has left her isolated, raised by her father’s strict rationality and his memories of her Taíno mother. She’s odd, conflicted, and longs to be independent.
I really wish that this novel had been narrated from Isabel’s perspective. Not only would her story have offered a fascinating insight into a juicy ethical dilemma, but I wouldn’t have had to put up with Lucas’s first world problems as much. There was a lot of build up about the house on Calle Sol and its mysterious inhabitants at the beginning of A Fierce and Subtle Poison and, despite Lucas’s very interesting hallucinations, the narrative didn’t do enough with the stranger elements of backstory for me. Instead, I was left with an easily solvable puzzle and a dose of disappointment.
