Bloody Valentine isn’t a full book in the Blue Bloods series. It’s a side book, fan service and an effort to fill in some empty blanks in the story. There are three novelettes between these covers.
Just Another Night in Suck City deals with Oliver, his struggle to fight both the bond between he and Schuyler, formed after she drank his blood, and her abandoning him for Jack. When I saw the state Oliver was in it made me hate Schuyler quite a bit (which probably took some of the enjoyment from the third story, but I’ll get to that.) Luckily vampires aren’t the only creature lurking in the streets of New York. Oliver meets a witch who helps him heal, and boy does he deserve it.
Always Something There to Remind Me takes readers back in time to Allegra and Charles’s childhood, or rather teen years. Feeling just as stifled by the destined bond to Charles, Allegra falls for a human (the man readers know to be Schuyler’s father). This was probably my favorite tale of the three, but I still don’t like Charles.
Finally is Ring of Fire, the very sweet, outright sappy story of Schuyler and Jack’s bonding ceremony. It has some fighting and danger (and Bliss and Oliver, which made me happy because honestly the Jack and Schuyler love each other relentlessly bit gets a little stifling) and yeah, the wedding itself is all aww-worthy.
If you’re a fan it’s worth the read, filling out the Blue Blood world even more. But it doesn’t further the main plot so you won’t be lost if you don’t pick this one up.
