Glee actor Chris Colfer’s first book is set to top the New York Times bestseller list.

The gay star’s debut, The Land Of Stories, is a children’s book.

Earlier today, he tweeted: “#TheLandOfStories is debuting at #1 on the New York Times Best Seller’s list!!! Never in my wildest dreams did I imagine this. Thank you!!!”

Colfer said recently he has already begun working on a sequel to the debut novel.

Last year, when his book deal was announced, the star said: “When I was ten years old, I promised myself that if I ever had the opportunity to write this book, I would jump at the chance.

“This book has been at the core of my imagination for a long time and I’m excited and nervous to share it.”
