Hi,

Please can you tell me if you like this cover or should I change something?

it’s for my fantasy novel, here is the synopsis:

For twelve years, the power has been usurped at the Realm of Harcilor.
Cyr, an erudite, and his adopted son, Kaaz, have formed a secret school.

Indeed, in this world, some people were born endowed with magical abilities : the Silarens.
However, it is not that easy to detect your own powers.
They will soon be joined by a mysterious young woman who will provide them with valuable information.

When Litar - the most powerful being of the realm - goes away for two months, they finally foresee the opportunity to act.
Can they win their freedom back? Will they make the right choices?

Thank you very much!
