The Stars Inside Us - The Broken Stars, #3

She'll burn it to the ground.The ashes have settled since Calay's harrowing escape back to Earth, but the threat from the Others-and humanity itself-hasn't. After surviving devastating losses and impossible choices, Calay drags herself to the doorstep of the one place she never wanted to return: The Resistance. Forced to trust hidden motives and questionable loyalties, Calay intimately knows the only way they survive, is together.
But as she dives deeper into alien territory, her new reality is even more alarming than she could have anticipated. A perma-winter has settled over the planet. A strange new league of mutations has emerged amongst the Others. And despite her best efforts, past decisions come back to haunt Calay-taunt her. It doesn't take long for her plans to go horribly wrong. Her terror is compounded when she realizes she's not only trapped with the enemy-a group that would gladly kill her if they knew her secrets-but that she's actually started to care for them; especially Briar, the tea-loving, open-hearted woman who makes Calay feel like home.
In these final dying days, stars collide and the darkness within ignites. The world's future is in Calay's hands and she must decide what's more important: saving herself, or saving what makes us human. Hopeful and devastating, The Stars Inside Us is the third volume in Kristy Gardner's enthralling queer sci-fi series, The Broken Stars.
