You know a lot about the famous Tony Stark, but perhaps nothing about his older brother, Gregory Garcia.
In his first book titled "Graphene Man Genesi" the eventful birth of the brothers is narrated. If you want to know a great story, you are in the right place.
The story begins when the parents of the twins meet. Later, due to job incompatibility, they must change their lives and as the beginning of this new stage, they undertake a vacation in Spain (Europe).
A fortuitous accident will separate the brothers perhaps forever.
