What really happened that night

Harry Potter lived with his Aunt and Uncle. His parents had died by the hand of Voldemort. In Harry's third year, Hermione gets a cat by the name of Crookshanks. Crookshanks is actually Lily Potter. She survived and was an animagus. But she can't tell Harry until he is ready. Also I would siriusly (ha see what I did there) appreciate it if you guy told me if this is good or not. It is not finished. (BTW the plot is mine but all the characters are owned by J.K. Rowling)
J.K. Rowling if you read this, I doubt you will, but if you do I would like to say thank you for creating such and inspiring book that has made me want to read more and more. Really Thank you so much.

Please R&R
Thanks!
