Hairy Harmony. Another solid entrant into this series, this time featuring the one natural child of the unifying parents of all five brothers this series revolves around. As with every other entrant here, if you don’t mind minor (and sometimes not quite so minor) spoilers about previous books, this one is perfectly fine as an entry point into the series. Solid MM romance with a rather shocking ending given how this series has been built to this point, and as with every other book in this series introduces the next brother and features him fairly prominently. (Including a rather interesting revelation about that particular brother’s mysterious past.) Very much recommended.
