Arena of Antares is a science fiction novel by British writer Kenneth Bulmer, written under the pseudonym of Alan Burt Akers; it is the seventh volume in his Dray Prescot series of sword and planet novels, set on the fictional world of Kregen, a planet of the Antares star system in the constellation of Scorpio.

Prescot returns to Yamman, commanded to do so by the Star Lords, narrowly escaping a number of Canop galleys on the river.

Overconfident, the Miglas attack against Prescots wishes and force a battle the Canops ultimately win.

Prescot fights the teleportation but loses and finds himself having to rescue a group of people who he later learns were plotting the overthrow of Fahia, the evil Queen of Hyrklana and twin-sister of Lilah who he had encountered at Faol.

Prescot plots his escape but, as on previous occasions, the Star Lords interfere, raising a powerful storm to prevent his departure from the capital of Hyrklana.

She intends to send Prescot to a slow death but a young noble recognises him as the man that saved them when they were conspiring against the Queen.

He surrenders his sword, conscious that he was prevented from escaping Hyrklana for a reason and manages to pacify the Queen.

The conspirators wish him to kill the Queen in one of his private meetings with her but he refuses to commit the crime of a cold blooded murder of a woman.

He learns that, for Delia, their last separation was only four days ago, another instance of Prescot being in a time loop, and that she followed him to Hyrclana after hearing him say he did not want to go there during his forced departure.

Prescots friends of the Red Drang assist him in the fight by taking the Krozair long sword to him which he uses to defeat the Boloth.
