Plagiarized Book Of Other Author And Upload Another App Without Asking Or Taking

hello sir/madam, my name is nawab shaikh. I'm taking one book copy(plagiarized) from the Inkitt website/app without asking the original author and upload to another writing app for making money. In this lockdown, I want to make money that's why I stole this author's work. I know but now he complains about this book on kongfu book app. kongfu book app team find the work is stolen without asking the original author. kongfu app team delete my book. But now the author takes legal action against me. he sends me a mail and says that he will send me lawyer notice. What I can do I don't know. How I can survive this situation. I apologize for this. please help me. I don't want to go to jail.
