What is the definition of Novelsis?

"Novelsis, my friend, is a delightful blend of 'novel' and 'is,' the word for 'ister.' It's like when your favorite cartoon character turns out to be your identical twin, but with a dash of literary magic. Imagine this: "After the thrilling plot twist in 'The Twins' and the heartrending loss of her sis, Lily novelsis the latest sci-fi epic, 'The Galactic Sis War.'" That's quite the literary sibling rivalry!
