I'm actually repeating my review of the second book:

I really liked the first book, a random Kindle Unlimited find.  This was also a fun read, definitely edited and ready to be published.  At time I read, it was also in KU.

After enjoying the first book so much, I immediately binged the next two books.  I recommend the books and the series but not to binge them back to back.  Because the books are good with excellent story flow -- the series not so much.  Not sure how to explain except the three books I read don't seem to belong together despite a shared main character.  Oh, there are a few bits getting on with expected plot, careers and romance.  But the main character just seems after first book to be thrown into settings and circumstances that don't seem to mesh with previous book -- maybe even completely different genres for each book.

He missed having dust bunnies to chase after, and he was no match for the vacuum monster, much as he tried to kill it when it was sleeping in the cupboard.

There was a shaft of sunlight hitting the bedroom floor. At this time of day, Brutus always found it something of a dilemma. Was it better to lie in the shade but on the comfort of the bed, or to lie in the sun but on the hardness of the floor?

Every time I was in a life-or-death situation, I started to think I should lead a healthier lifestyle. The trick was to start avoiding life-or-death situations.
