"Looking back, my time on Dance Moms seems like a whirlwind of dancing …but also fighting," the 15-year-old writes in an exclusive excerpt to PEOPLE

She may only be 15 years old, but Dance Moms alum Chloe Lukasiak‘s list of achievements continues to grow. The latest addition? A new book!

“It’s definitely stuff I don’t think my fans know about me,” Lukasiak exclusively tells PEOPLE of her book, Girl on Pointe: Chloe’s Guide to Taking on the World. “It’s the ultimate behind-the-scenes of my life. It’s something really close to my heart. I’ve always been the self-proclaimed nerd of the group. I love reading and writing so this just seemed so natural and so right. It’s been a crazy journey so far.”

Lukasiak, who spent the first four seasons on Lifetime’s Dance Moms, suddenly left in 2014 after her coach, Abby Lee Miller aggressively mocked her physical appearance in public.

“The reason for leaving the show was my old teacher mocked my eye very bluntly; I was dealing with some serious health issues,” says Lukasiak. “[My exit] was very abrupt and I didn’t expect to leave obviously.

“Looking back, my time on Dance Moms seems like a whirlwind of dancing …but also fighting. The parents were always fighting — with one another, with Abby. Anyone who’s watched the show knows about these fights,” she writes.

She adds: “In any case, after the first season, we girls learned to make the most of the situation. Obviously, the show was high-stress and intense. Obviously, there was conflict. But we decided to ignore the bad; instead of listening to the fighting, we figured, ‘let’s just go have fun!'”

Though Miller recently announced her departure from the series after seven seasons, the show must go on. This time with dance expert Cheryl Burke.

“Cheryl is really, really amazing,” Lukasiak says. “She’s so encouraging and she’s always trying to bring out the best in us, but in the most positive way. She’s always pushing us. I’ve only known her for a few weeks but I’m honored to be able to say I’ve been trained by her by a short amount of time. It’s been

Though Lukasiak could not confirm whether or not she will be featured on season 8, the social media posts speak volumes.
