I need a quick paragraph about an alternate outcome for the book refugee quick

I never read that book, but I'll try to make a paragraph (T_T)/

Refugee had great (but sad) endings. I was really happy to hear about Isabel’s life in Miami and how all of her family members and the Castillo’s were doing. Mahmoud’s story had a surprising  ending because this old jewish lady (that turns out to be Ruthie) and her husband let Mahmoud’s family live in their house. The saddest part Ruthie told Mahmoud that Josef and her mom when to the concentration camp and died there:(. The most upset part was when the story said that Josef chose to go to the concentration camp instead of Ruthie, so she could stay alive. I thought it was so cool that all 3 of the stories connected in the end have Mahmoud family and Ruthie’s family living together and Isabel’s grandpa having something to do with the SS.St Louis docking at Cuba. I think in all Refugee was a really great book. Mahmoud's story had a surprising ending because this old jewish lady (that turns out to be Ruthie) and her husband let Mahmoud's family live in their house. The saddest part Ruthie told Mahmoud that Josef and her mom when to the concentration camp and died there. Josef later dies in the camps, along with Rachel. Thus, Josef's tale emphasizes how the trauma of being a refugee often forces a child to grow up far sooner than they should have to, expediting their coming of age. The end, showing the impact of a book.
