No story progression, I feel like we're just reading the same story again. Like book one where Daniel gets hurt, sleeps with Mace, gets hurt again, rinse, repeat. In the last few it's someone gets hurt, go to compound, fix them up. Rinse repeat. The teaser of Mace remembering things from his prior live from book two is completely dropped and that's so disappointing. So much potential wasted. Also these books are too short and too expensive. This should be a trilogy at best, not 5 books.
