No more hiding. I will bring the fight to Nexis... and destroy the last ruby.
Once and for all.

I’m done playing nice.

I am the Seer. It’s time to play the role I was made for.

My mission is clear. Now it’s about gathering the resources I need to take down the world’s biggest, baddest, secret society.

I’m not alone this time.

With all three of the Chosen Ones on the same side, we’ve got one last shot to make history.

And destroy all of the Nexis Society’s hopes and dreams.

Are you with me?

Montrose Paranormal Academy, The Last Ruby is the final chapter in the 5-book Clean Academy Paranormal YA series for teens. It’s a saga full of slow burn romance, snarky dialogue, and urban fantasy adventure set in New York City. Think Shadow Hunters meets Darkblood Academy with a dash of Harry Potter ... as a girl.

A satisfying end to the series, this instalment wraps up everything perfectly and we learn more about The Messenger. The powers of The Messenger intrigued me from the start, since this is a Christian book, there is no swearing or inappropriate romantic gestures.
The ending felt somewhat unrealistic that practically all of her friends lived that were alive in this book. The fast-paced plot and diverse mix of characters, and especially the prominent role of magic makes this an enjoyable read. It also isn't very long.
Overall, a satisfying conclusion imbued with tidbits of romance and some action.

This is the final book in this series, and I think the author did a wonderful job of wrapping it all up. There was heaps of action, bits of romance (but not too much - it's a Christian book), angels, demons, and great characters galore. There was also some areas left open for a possible second series. Overall, I really enjoyed this series. It's young adult, and I'd feel comfortable having my kids read it. And the storyline was fresh. That's hard to find! Fun read!

Young adults, and fantasy readers in general, should enjoy this exciting conclusion to the Montrose Paranormal Academy series.

Having read the previous books, I was keen to see what happens to Lucy in the series finale.

The story picks up from book 4, with Lucy, her reunited family, and close friends once again on the run from the evil Nexis Society. The action keeps coming, enhanced with far flung backdrops including Kuwait and an abandoned temple cave system in India.

I enjoyed the fast-paced plot and diverse mix of characters, and especially the prominent role of magic. I think fans of the series will enjoy this concluding book, and I look forward to reading more from this author.

In anticipation of this final book of the series, I binge-read all previous installments, and let me tell you it was totally worth it!!!! I loved the series from book 1, and I was anxious to find out how the story ended. This final installment ties up everything together. There's action, adventure, magic, sweet young romance, and a stunning finale that had me smiling with utter satisfaction. Not to mention that there are hints of more stories to come? I sincerely hope Barbara Hartzler will write a sequel with Paige's story!!!

Enough rambling! If you like young adult paranormal academy stories with a dash of romance and plenty of action, one-click the whole series and binge-read to your hearts content!!!

The Last Ruby by Barbara Hartzler is Book 5 in the Montrose Paranormal Academy series. Lucy, her family and friends are again on the run. The Nexis society is hot on their heels. Realizing they need help getting the last ruby, they seek help from the Guardians. This conclusion to the fast paced, action packed series is excellent. The wonderful plot, exceptional characters, and the magic have made this an awesome read and series which I highly recommend. Received an ARC and this is my voluntary review.

In Montrose Paranormal Academy book 5: The Last Ruby by Barbara Hartzler the Seer, Lucy, is done playing nice. No more hiding. The mission is clear, bring the fight to Nexis and destroy the last ruby. She is not alone this time. She has the two other chosen ones with her along with other allies. This is the final book in this great series that I received through bookfunnel. I highly recommend this and the other books in the series. This book is available on Amazon

Ending war

I loved reading this series. Although this was the ending of the war between the three secret societies, i would very much like to see more of what these characters do moving forward.

The plotline kind of works, but nothing special. The little girl crush on every cute guy is over the top and kills any value in the series. I can't believe I read the series with this kind of girlie infatuation with guys throughout the books.

The Seeer

This was a great ending to an amazing series. Can't wait to see what she has in store next. I hope it will be just as good as this one.

I loved it!

It was so enticing that I couldn’t put it down, this book grabbed my interest from the very first page. I had to know what happened next. The story is well written with a very good storyline. Welcome to Montrose Paranormal Academy. Where Three Societies rule everything. The end has come, which means no more hiding. She brings the fight to Nexis and destroy the last ruby. She is done playing nice. She is the seer and it’s time she plays the role she was made for. The mission is clear, they just need gather resources needed to take down the world’s biggest and baddest secret society. She is not alone, all the three chosen ones have joined forces and are on the same side. She also has her reunited family, and close friends once again. They are again on the run from the evil Nexis Society. The action keeps coming, enhanced with far flung backdrops including Kuwait and an abandoned temple cave system in India. They have one last shot to make history and destroy all of the Nexis Society’s hopes and dreams. Lucy never wanted to be the Seer but she makes the best of it. When the rebel group realizes they can not get to the last ruby without the help of the Guardians, a negotiating team is sent to their 4th Sector Headquarters to make a deal for the Guardians help in destroying the last ruby. So with all that and more this story pulls you in and holds you tight. I absolutely love the ending. I can’t wait to read the other book series from this world. I highly recommend to everyone.
