Story of a time traveler

Rhyme is just a normal student who aspires to become a successful scientist one day, got accepted at Columbia University in New York. She just landed in New York from Paris to fulfill her dreams. But life has something else in store for her. What happens when a science student gets the key to time travel on the same day as her friend whom she loves dies in a car accident? Will she be able to save him by going back in time and breaking the rules of time travel? I won't give out any major spoilers in the synopsis. Read to find out more.... It sounds like a boring typical sci-fi novel but trust me, it's gonna be an emotional roller-coaster. I have tried to cover various genres like romance, fantasy, comedy, thriller, suspense, aliens etc. It won't be as boring as your science class, but I can promise you one thing, it will be 100 times more fun!! P.S. : This is my first novel so please ignore any grammatical mistakes. Also, my updates might not be regular as I am still studying (in final year of high school). Please forgive me for that, and enjoy the novel!
