It was a story about a young man becoming God, a lot of mathematics about the days between he gains more and more power.
It's NOT Dejavu Ascendancy!
He controlled hurricans and the atmosphere,
He had a girl friend who became a doctor, she broke with him because of his powers and then came back for his help curing one of her patients. At last he could control the whole universe.
any hints are appreciated.
Thanks in advance
