What is the resolution of the book "The Heir"

The book ends with Eadyln, (main character) find out that her brother Ahren had ran away and gotton married to his girlfriend as soon as her mother agreed without anyone knowing.

Explanation:

He leaves a letter for her and why he left. He loved her sister very much, but eventually he chose his soulmate. He explains to Eadyln and compares the two girls.

Thus, Ahren advises her to open herself to her people, to be brave and feminine at the same time and above all to find love in her life.

Eadlyn is angry and hurt by his words and his departure, but when she goes to her parents’ room to inform them about the letter, she finds photos of them during their own Selection, their wedding and the birth of their children. Eadlyn recognizes that her father had modeled this room as a shrine of his love for her mother. Fully realizing now the love her parents share, she can understand why Ahren chose his girlfriend over his family.

At that moment though, she learns that her mother has had a heart attack, after hearing about Ahren’s elopement. She runs to the hospital wing, where she finds her father crying and General Leger comforting him, both of them hoping for the best. Marlee, Kaden, May and the Selected Men also come to pray for America’s recovery. Afraid of losing her mother and after seeing all those people around her and the bonds they share with each other, Eadlyn finally realizes the importance of love in her life.
