The couple cannot return home as there are dangerous monsters that are looking for their powers and they will just tear them apart if they catch them. Icarus is the second titan who is gorgeous in appearance and that is another problem for the young human who is falling for his charm as well. Eliza Raine talks about the treasure very late in the novel.
The treasure is a box hidden in the academy and if the titans are able to deliver it to Zeus, they would be allowed to stay. Kathleen Li has given the female character a more powerful voice because everything revolves around her in the end. The Immortality Trials and Surrender of the Brutal King don’t possess such characters for sure. This is a great book in which we finally see the rise of the titans and we also come to know why Zeus was scared of them.
