Mmm. I have Kindle unlimited and I usually do a bunch of searching and build up a list then go through them and repeat. I have a bad habit that if a book isn't that great and one of the other books looks more appealing I put it down and don't muster the interest to pick the first one back up after I finish the second.

Hall of blood and mercy trilogy K.M Shea Either 4 or 5 times. I just love the books so much with the whole world she introduced. It's also an interesting concept with the modern take on vampires (so so much better than the old just a monster type) and the other supernatural races intermingling as magic is slowly dying. And also it's clean that's a huge bonus!

Also Quantum League Spell Robbers by Matthew Kirby. 5-6 times. A great story about actuations (basically his sifi take on elemental magic.) This one is also clean but focused on a younger audience. Unfortunately the book has been out for a long time and his blog says the second is written but waiting on the publisher and hasn't been updated in all that time.😞
