Because It Is My Blood

This is the sequel to All These Things I've Done by Gabrielle Zevin (see my post here). Anya served her time at Liberty while her sister, Nataliya, was away at "genius camp" for the summer, but now all her friends are going back to school for their senior year except Anya. And no school will take her because of that little incident with bringing a gun to school and shooting someone. Apparently Win has found a new girlfriend while she was in prison and things are getting even more complicated with the running of Balanchine chocolate, so Anya decides to take up an offer to go spend time at a cacao farm with relatives of her cousin's wife, Sophia. There, the Marquez's son, Theo, takes Anya under his wing and shows her the ropes of growing cacao. Anya is surprised by a proposal of marriage from Yuji who wants to consolidate their respective businesses, but Anya turns him down.
Things take a decidedly dark turn when someone tries to assassinate Anya and Theo is seriously wounded instead. Anya heads home to find out there had been an attack against her sister on the same day, but Imogen stepped in the way and was killed instead. She also learns that Leo has died at the same time in a car bomb. Scarlet is pregnant and finally decides to marry the father, Gable Arsley, in spite of his endlessly bad behavior. Anya takes and passes the GED since she can't attend regular schools. Struggling to find a way forward, Anya comes up with a scheme to open medicinal cacao shops and hires Charles Delacroix to be her lawyer. He is at loose ends after having lost the election for District Attorney. Anya eventually learns that it was her cousin and his wife, Mickey and Sophia Balanchine, who orchestrated the attacks and are trying to take over the business and get revenge for Leo shooting Mickey's father. It's hard to know who to trust if you can't trust family.
