Blood Red Horse Chapter5 HUM

I want to write about what I've found so far.
There are two brothers. Gavin and Will. Gavin is an older brother, Will is an younger brother. When they get together, they always fight each other. Once Will hit his older brother, and Gavin was bleeding. A girl appeared call "Elie". Elie is a really grubby girl who wears dirty clothes.
Elie swears at Gavin with Will, and it's because of Elie wants Will's profits. Elie will have to marry with Gavin in the future, this is because Gavin is son of the Sir Thomas and Elie is also from a castle , so they really connected each other, and here you might have a question. Why can' Will marry with Elie ? In the middle ages in Europe, when older brother could not get marry, then younger brother should wait until older brother gets married.
Will loves horses, he has a Scremanta, and it's light and speedy. However he complains about having Sacremanta. He wants more powerful horse than Sacrementa, such as a Stallion.
Will and Gavin are son of the Sir Thomas.
Once Sir Thomas attended a war, and he did not spend much time on build Hartslove Castle(There were a lot of deers around the castle, so they called it Hastslove castle). Therefore Hastslove Castle became a useless building.
Time passes and passes, Will becomes more professions on horses and wars.
The whole stories are about two boys and one girl. The adventure of a lifetime.
