## Summary

BookSirens promotes each accepted book to its reader community for three months, delivers ARCs securely and sends review reminders. It reports that about 75% of downloads lead to a review on average, but guarantees neither reviews nor ratings. You pay BookSirens to find readers, not readers for reviews: Amazon permits free copies only if a review is not required and not influenced, and offering anything more invalidates the review.

## Pros

- Pay-per-download option lets you cap spend per book
- No per-reader fee for readers you invite yourself

## Cons

- Books must pass its acceptance criteria
- Downloads depend on your cover and blurb; none are guaranteed
