I've been outlining my first novel for many months and I've always had a vague idea for a sequel, but today I had SO many awesome ideas for a prequel!!!

Looks like I'm gonna write a trilogy, boys 🤘

Question tho --- since "book 2" is my original idea and I'm so far along working on it, should I finish it first before starting on book 1? Or should I write all 3 books as one big project? (because I'll have to release them all at once or at least very close together)
