10 out of this world books to celebrate International Women’s Day

Wealth. Power. Murder. Magic. Alex Stern is back and the Ivy League is going straight to hell.

Find a gateway to the underworld. Steal a soul out of hell. A simple plan, except people who make this particular journey rarely come back. But Galaxy "Alex" Stern is determined to break Darlington out of purgatory, even if it costs her a future at Lethe and at Yale.

Thick with history and packed with Bardugo's signature twists, Hell Bent brings to life an intricate world full of magic, violence, and all too real monsters.

With the dangerous, erratic Princess Sophia imprisoned, Queen Charlotte decides to invoke the ancient tradition of The Beauty Trials-a series of harrowing tests meant to find the one true ruler of Orleans. Edel, who has always aspired to be more than just a Belle, decides to enter and, after promising to bind her arcana to keep from having an unnatural advantage, joins a few dozen other hopefuls intent on becoming the next Queen of Orleans.

But the trials are far worse than any of them bargained for. As the women are put through dangerous tasks meant to test their strength, many perish, and Edel is mysteriously attacked by one of the other competitors-forcing her to use her powers just to survive. Will her subterfuge cost her the crown, or is there a larger conspiracy at play?

On the other side of the Shadowpass, rebellion is brewing and refugees have begun to trickle into the city at the edge of the world. Looming high on the cliff is The Nest, a fortress full of mages who offer protection, but also embody everything the rebellion is fighting against: a strict hierarchy based on magic abilities.

When Isha arrives as a refugee, she attempts to fit in amongst the other mages, but her Kher tattoo brands her as an outcast. She can't remember her past or why she has the tattoo. All she knows is that she survived. She doesn't intend to give up now.

Tatters, who wears the golden collar of a slave, knows that this rebellion is different from past skirmishes. He was once one of the rebels, and technically, they still own him. He plans to stay in the shadows, until Isha appears in his tavern. He's never seen a human with a tattoo, and the markings look eerily familiar…

As the rebellion carves a path of destruction towards the city, an unlikely friendship forms between a man trying to escape his past and a woman trying to uncover hers, until their secrets threaten to tear them apart.

Silence has fallen. The Psy are free to feel emotion. Free to love. But Silence was never a prison for Ivan Mercant.

The biggest threat to his future lies dormant in his brain - a psychic monster that wants only to feed. And now, the brutal leash he's kept on that monster is slipping. He prepared for this day, for the end of Ivan Mercant…but that was before he met Lei.

As primal as she is human, this wild changeling brings colour into his life, laughter to his soul. Then the dream shatters in a rain of blood, in silent bodies in the snow. Lei is gone. Vanished without a trace…until Ivan meets strangely familiar eyes across a busy San Francisco street.

Soon, a deadly soldier who believes himself a monster and a broken healer might be all that stand between life and death for the entire Psy race…

Tanta and Cole may have stopped the mass murder of InTech's residents, but the cost was severe. Despite their efforts, Harlow 2.0 - the update to InTech's mind-based operating system - fed out. Now its citizens are compliant zombies, and Tanta and her crew are trapped underground.

All except for Fliss, who has no system to update. She alone can go outside, and it's Fliss the crew are relying on to help get them out.

For only then can they dismantle the damage Harlow 2.0 has done. If Tanta, Cole and InTech's residents are to truly be free, it needs to be destroyed. But Tanta knows that task will put her on a collision course with the corporation that raised her, her oldest friends, and the woman who was once her soulmate.

And this last mission might ask more of her than she's able to give.

Rice Fish: sentient ship, leader of the infamous Red Banner pirate fleet, wife of the Red Scholar. Now isolated and alone, Rice Fish wants Xích Si's help to find out who struck against them and why. Marrying Xích Si means Rice Fish can offer Xích Si protection, in exchange for Xích Si's technical fluency: a business arrangement with nothing more to it.

But as the investigation goes on, Rice Fish and Xích Si find themselves falling for each other, and soon they will have to make a stand-and to decide what kind of future they have together...

From the start, terraformer Lucian is intrigued by nine-year-old Nou, silent since a horrifying incident that shook the base and upended her family into chaos. If he could reach her, perhaps he could understand what happened that day – and what she knows about the secrets of Pluto.

Nou possesses unspoken knowledge that could put a stop to the terraforming. Gripped by her fears, unable to trust her family, there is no one she can talk to. Only through Lucian's gentle friendship will she start to rediscover her voice – and what she has to say could transform our understanding of the Universe.
