Publisher: Razorbill
Goodreads Summary: 
Book 3 in the breathtaking sci-fi space saga inspired by astrology that will stun fans of the Illuminae Files and Starbound series.

One final secret stands between Rho and the enemy. But will the devastating truth be enough to destroy her first?

Rho, the courageous visionary from House Cancer, lost nearly everything when she exposed and fought against the Marad, a mysterious terrorist group bent on destroying balance in the Zodiac Galaxy. Now, the Marad has disappeared without a trace, and an uneasy peace has been declared.

But Rho is suspicious. She believes the Master is still out there in some other form. And looming over all are the eerie visions of her mother, who died many years ago, but is now appearing to Rho in the stars.

When news of a stylish new political party supported by her best friend, Nishi, sends Rho on another journey across the galaxy, she uses it as an opportunity to hunt the hidden master and seek out information about her mother. And what she uncovers sheds light on the truth–but casts darkness upon the entire Zodiac world.
Rating: 4.5 Stars
Wandering Star Rhoma Grace continues to travel around the Zodiac searching for the master. She journeys to House Aquarius in her quest to find her mother and support her best friend Nishi, a member of the newly formed Tomorrow Party which promises freedom from the twelve seperate lifestyles.

Change is a huge part of Black Moon and I love how Romina Russell conveys each character's feelings throughout this process. A lot of  personal and political issues are brought to the center stage. A resolution which I kind of saw happening occurred and though I wasn't too surprised, I was sad the past finally ended. Nishi's feelings are a small subplot, a little interlude which strengthens Rho's resolve.

As always Rho's dreams are a huge part of the book, but in this novel Rho truly begins to search for her true self, the woman she is destined to be. She questions the facts and thinks for herself, acknowledging her fears but not letting herself be paralysed by them. Kassandra is a further representation of how different stories can lead to a whole new lifestyle.

Black Moon tells of the positive and negative sides of Zodiac. The master's identity is revealed, a shock to all, one unsuspected individual who had every reason to be the master, but wasn't discovered. The clues are there, you just have to read into them a little more deeply than I did. The ending shows us inner darkness and the utter heartlessness of some characters, people who may truly have no conscience and are irreversibly evil. This book will make you question everything you believe is set in stone.
