I really want to give this book 2 stars since it's targeted for a younger age group than what I'm used to, but I didn't feel that it was fair to "punish" the book because it really wasn't for me.

First, I do think that it's interesting that Tubb made a story about the big news a year or two ago when someone entertained the idea that there was really a 13th sign in the zodiac. And I think it was a fun book to read because the book was filled with action as Jalen and her friends faced down each "ch

The 13th Sign starts off with an interesting concept. What if everyone's personality shifted? Would it be chaos? Political leaders suddenly indecisive? Surgeons suddenly squeamish?

However, the 13th Sign fell a bit flat for me. While there was quite a bit of action and Tubb spelled out the lessons in the book pretty explicitly, it lacked the spark that makes a book great.

I'm fairly indifferent towards the main character, Jalen. There was nothing in particular that I disliked about her, but I jus

THE 13TH SIGN has a creative and fresh idea involving zodiac signs, but unfortunately it fell flat in its execution. I loved the idea of Zodiac signs being real creatures and that a shift in ones sign means a shift in your personality. Although, considering most horoscopes are pretty general in their traits and could be attributed to many people, the extreme and sudden shifts in personalities and actions were too extreme to believe for me.

The 13th Sign. When I first heard of it, I literally spazzed. What a brilliant idea! Like Jalen, I am a Sagittarius that feel like the horoscope didn't depict my personality right. And so I started wondering if there was a 13th sign. The idea intrigued me dearly. And recently I got into looking at horoscope more because of Midorima from Kuroko no Basuke (I miss you Shin-chan). So when Raincoast Books provided me a copy of The 13th Sign, I freaked. So on the night of January the 4th, I started r ...more

I was told a few weeks ago that whenever I review a middle grade novel I talk about how surprised I am by it. So I am going to switch it up in this one and say that The 13th Sign was a refreshing read. Something about the innocence of the characters and the genres ability to get me to go along with whatever fantastical plot the author throws at me, gets me everytime. This one reminded me a lot of Jumanji, the releasing of ancient magic and the race to put it back in its place.

How much does your star sign affect your personality? According to the 13th Sign, it completely controls it. When Jalen unleashes the 13th zodiac sign, she changes the personality of everyone, including herself. This personality shift of all the characters did inhibit my ability to connect to the characters, as I wasn’t sure what they would do with the new personalities vs their old personalities. Ellie, Jalen’s best friend, is impersonated TOO well by Gemini, and the fact that Jalen couldn’t fi ...more

That hype and virtual mayhem that Ophiucus created was enough to make me interested in this book. It started of with 14 year old Jalen getting a reading for her birthday. It was a tradition started by Nina, her once bright and adventurous grandmother who's now fighting to live on. Jalen just wants everything to be okay. Maybe being a Sagittaruis wasn't helping her at all. And so she found a mysterious book about the zodiac, and in her persistence to unlock it, she

Initially, when I first started reading this book, it stalled for a little while, it was a little slow. I was at first also confused what was goin
Okay, I feel like this book needs a few things going into it. You either need toreallybelieve in astrology -- like, awholelot -- or, if you don't believe in it, you have to be completely willing to thoroughly suspend your disbelief. I fall into the latter category. But how many fantasy worlds do we really believe are actually real? Um, if you're like me, none of them. So I was totally willing to jump into the fantasy world of this book, where personalities really are determined by your Zodiac si ...more

This is an extremely well crafted story that draws you in and doesn't let go. Traveling along with Jalen on this magical/mythical journey was great fun. There are so many facets to this story. Not only does the reader learn about characters and the things that take place inside their heads, but the reader will also imagine his/herself in the story and wondering how he/she might change if the zodiac were somehow shifted.

I always loved checking my horoscope as a kid. This book taps right into the mystery and desire to categorize oneself during early teen years. Hot air balloon rides, New Orleans streets, and magic—who could ask for more? I loved it.

The 13th Sign is a refreshingly novel idea for a story that is carried off with an abundance of action and intrigue. I love the way Kristin Tubb impersonated all of the zodiac signs in original and unpredictable ways while still keeping them true to their legends. Believing in horoscopes or not is irrelevant if the reader will allow the fantasy element of this story to lead the way. She also provided a surprise ending and a nice tie up to all of the unknowns in the novel. The book is strong with ...more

i enjoyed this book, i really do, with all the astrological horoscopes and a 13th sign that can change everything! plus the progress of the story and the whole plot of the story and the twist and uniqueness of the challenges.

Book: The 13th Sign

Every birthday, Jalen, would go to a fortune teller to see what her future is and what her Nina's future is (Nina had Cancer). But every time Jalen would go, the fortune teller just could not tell what zodiac sign Jalen had. One night, when they were exploring the fortune tellers shop, they find an old book called the, The Keypers of the Zodiac. It had been rolled up in a lock. Jalen and Ellie leave the money on the table and sneak out with the book. Thinking the lock looked s

I don't read a whole lot of Middle Grade, but after hearing Kristin talk about her book The 13th Sign last year at a book signing, I was really interested. I don't really read much into horoscopes or anything like that, but that doesn't mean I'm not interested in them. I love the premise of this novel and I've read a few books that have discussed Opiuchus now, so I was definitely intrigued by this one. With the incorporation of a new zodiac sign, that would mean many people's signs would change, ...more

When Jalen’s trip to a Voodoo store on her 13th birthday gets her a disappointing horoscope reading, she acquires a locked book called The Keypers of the Zodiack and naively unleashes the 12 keepers of the Zodiac, as well as a dangerous and hidden 13th sign, a snake. Now she must battle each protector to save the world and return her friends and family to their usual personalities. Can she save the world in only 1 day? I have to admit, I didn’t love this book. It felt slow, and contrived, but fo ...more
The 13 Sign was an interesting book, Kristin O'Donnell Tubb did a great job keeping readers interested, you never quite knew what was going to be around the corner. How the author changes the personality of everyone was kind of odd though, they had almost the opposite personality but not quite.

4.5 / 5

I had the pleasure of meeting Kristin at the 2013 Midsouth SCBWI conference. I was even luckier to get my copy of The 13th Sign signed by her.

So why do I like this book so much?

Tons of reasons!

1) The hook. The 13th Sign is a totally unique concept. Sure there are books out there dealing with the Zodiac, but this is the first one I've ever read about someone unlocking a thirteenth sign that throws the entire world out of zodiacal whack. I mean, come on! How cool is that? Answer: very cool

My hands were both numb, but I managed to push the heavy basket in a circle, torching every shiny, nasty bug in sight. I think I was screaming, too. Because really, torching scorpions calls for it.

When Jalen inadvertently releases the thirteenth sign of the Zodiac, Ophiuchus, it realigns the signs of everyone in the world, changing their personality attributes to the point where she barely even recognizes her best friend, or herself. To the other signs, her actions are seen as a challenge, and

With the start of the Chinese New Year, I thought it would be a fun time to pick up THE 13TH SIGN by Kristin O'Donnell Tubb, which is based on the zodiac. For those not in the know, astrologically, there are thirteen constellations that cross the ecliptic, Ophiuchus being one of them, yet only twelve of these are in the zodiac. (Here's more info more info on Ophiuchus and the history of where it falls for those curious to learn more) Tubb looked at this when setting the foundation for THE 13TH S ...more

When I first started reading the 13th Sign I wasn't so sure it was for me. Jalen the main protagonist actually bored me a little in the beginning of the book and I kept switching her name to Jaden in my head. I would be lying if I didn't admit that I almost put the book down permanently. Since I requested this for review I really wanted to give this an honest shot. I am so glad that I did because to my surprise The 13th Sign turned out to be quite an enjoyable read!

Once the story picked up Jalen
I can’t be the only person who has ever been suckered by horoscopes. You guys, I went through a stage where I actually believed they were real and kind of a big deal — you know those horoscope predictions. Granted, I am a Cancer and I am very emotional and kind of a total home body — however, sometimes I really like going out. Just because I have not checked my horoscope in months does not mean that I’m not interested in astrology as a theme, though. Like, you guys remember in 2011 when there wa ...more

A journey rich with mythology, brimming with magic, and rip with lore, The 13th Sign is a story with an exciting adventure readers of all ages can enjoy. I really enjoyed the concept of this book. Not only does it entail something that's not been common in MG (middle grade) and YA (young adult) books, but the over all storyline connected with me. I remember being addicted to finding out what horoscope was when I was in middle school. I can't remember which magazine it was, but one of the teen ma

When Jalen finds a mysterious, locked book called The Keypers of the Zodiac in a voodoo shop in New Orleans, she is irresistibly drawn to it. But when she finds a way to unlock it, she sets off a chain of events that shifts the signs of the zodiac to make way for a new one, Ophiuchus.

Not only does everyone’s personality shift as their birth dates place them in a different sign than they were in before, but suddenly Jalen finds herself facing challenges from each zodiac. If she wants to make it o

I absolutely enjoyed The 13th Sign by Kristin O’Donnell Tubb, and I truly believe it is a story that MG readers will thoroughly enjoy. Why? Ummmm…because the twelve signs of the Zodiac come to life! Yes, you heard me…pretty awesomesauce right?

The 13th Sign opens up in a voodoo shop in New Orleans, and on main protagonists, Jalen’s, birthday! After many years of tradition where Jalen and her grandmother, Nina, come and get their tea leaves, palms, or tarot cards read. But this year, Nina is in th
