Amazon Blurb:

After her twin sister’s brutal murder, former US Army Sergeant Allison “Lex” Luther vowed to protect her niece, Charlie. So when two vampires try to kidnap the baby, it quickly turns into a fight to the death—Lex’s death, that is.

She wakes up to two shocking discoveries: she has miraculously survived the fight, and baby Charlie is a “null,” gifted with the ability to weaken supernatural forces…and a target for creatures who want to control that power. Determined to guarantee her niece’s safety, Lex makes a deal with the local vampires. She sets out with the mysterious—and undead—“fixer” Quinn to track down whoever’s responsible for the kidnapping, sharpening her newfound magic skills along the way. But the closer she gets to the truth, the more dangerous her powers become.

Boundary Crossed is a dark, thrilling journey into a world where the line between living and dead isn’t nearly as solid as it appears…


“What happened?” I asked.
“You fainted.”
“I did not,” I said crossly. “Fainting is for preteen girls and those really weird goats. I do not faint.”


I enjoyed reading this one. It wasn’t really much of a story about solving a dead body. It was about the main character protecting her baby niece. It was about her finding out about her powers and about the Old World. It was about her trying to get back to living. This book takes directly after the events in Hunter’s Trail in the Scarlett Bernard series, but you shouldn’t think you need to read that one to read this book. While the two stories are connected, they aren’t tied together in any meaningful way.

I liked the plot to this book. It wasn’t a detective roping in people he shouldn’t be into investigating murders. It really was just Lex trying to find a way to protect her niece and figure out this new world she is thrust into unexpectedly. It is her figuring out how all of a sudden, she is a power in their world. It is pretty interesting, honestly.

Lex is a good main character. She has a past that isn’t all a bed of roses, and Olson makes me care about it and about her (where she failed to do this with Scarlett with me). I care about Lex and about her plight. I want everything to work out for her. She makes some bad decisions, but they aren’t too bad, they’re mostly just reactive without all the information necessary to make a good decision with.

The world-building was solid. It doesn’t require you to have read the Scarlett Bernard series to understand what is going on. It introduces you to the Old World so that new people wouldn’t be left behind. This is especially important with the new series. It also doesn’t seem to contradict anything established in Scarlett Bernard, either. That was what I worried about was that the world would change depending on series with what the author needed. I’m glad this wasn’t the case.

Good book, much better than Scarlett Bernard ever was. A solid addition to this world Olson is building. I like Lex, I like her story, and I even like her choice of love interest.
