Quarantine by Greg Egan involves a quarantine of Earth by an alien species. (https://www.goodreads.com/book/show/1...)

So does Earth Quarantined by Richardson (https://www.goodreads.com/book/show/4...)

Do either of those remind you of what you are looking for? Do you have a timeframe? Remember the book cover?
