She thinks she knows who she is.
She is wrong.

A routine salvage mission uncovers evidence of a terrible crime and relics of a powerful ancient technology, just as Haimey and her small crew run afoul of pirates at the outer limits of the Milky Way and find themselves both on the run, and in possession of ancient, universe-changing technology.
When the authorities prove corrupt, it becomes clear that Haimey is the only one who can protect her galaxy-spanning civilisation from its potential power - and from the revolutionaries who want to use it to seed terror and war. But doing so will take her from the event horizon of the super-massive black hole at the galaxy's core to the infinite, empty spaces at its edge. Along the way, she'll have to uncover the secrets of ancient intelligences lost to time as well as her own lost secrets, which she will wish had remained hidden from her forever . . .

***SHORTLISTED FOR THE PHILIP K. DICK AWARD***

The last thing Sanda remembers is her gunship exploding.

She expected to be recovered by salvage-medics and to awaken in friendly hands, patched-up and ready to rejoin the fight. Instead she wakes up 230 years later, on a deserted enemy starship called The Light of Berossus - or, as he prefers to call himself, 'Bero'.

Bero tells Sanda the war is lost. That the entire star system is dead.

But is that the full story? After all, in the vastness of space, anything is possible . . .
Dazzling space battles, deadly galactic politics and rogue AI collide in Velocity Weapon, an epic space opera from award-winning author Megan E. O'Keefe.
