Oceanus

A starship drifts, its crew gone. The planet it orbits has no name. Survivors are separated on the surface. Exhausted. Hunted. Lost. The longer they stay, the less they can trust their own minds. Their captor is as patient as he is bent on revenge.

Review of Oceanus by Rusalka Books

‘The storyline of The Tempest is completely thrown on its head with this futuristic setting and the existence of Atlantis in deep space (not a spoiler). It was completely unrecognisable, yet all the puzzle pieces were there for me to assemble. I must admit, I did not put the pieces together, so the ending was a HUGE twist for me. But when I re-read it, they were definitely all there. For me, this is a show of truly skilled writing, because the clues Delaney wrote into different scenes were memorable, but not quite stand-out-y enough to make you immediately draw a full picture in your mind. And I love being in the dark when reading. It makes the moment the author switches the lights on so much more delicious!’ 🠖 Continue reading.

Review of Oceanus by The Word Dump

For such a brisk read Oceanus somehow packs in the feel of a slow burn into less than 200 pages— Which is no easy feat! There is a lot of build up as the events of the past unfold to explain why exactly Derrien and Thea are on Oceanus, as well as the role his brother and company played in his exile years before the onset of the novel.

More reviews for Oceanus

‘The characters are excellent, and I found myself sympathizing with and understanding all of them. When I finished Oceanus, I was immensely intrigued how Hanna had adapted or took inspiration from The Tempest, so I borrowed an audiobook and listened through it. I HIGHLY recommend reading Oceanus, and then the Tempest, because I found that Hanna’s book allowed me to better understand the play, and man, I am impressed with the creative way in which pieces are adapted.’

Everybody, like the play.

Oceanus is described as a dark, measured sci-fi thriller for readers who savour brooding isolation and the slow unravelling of betrayal and forgiveness in a hostile world. Oceanus is suitable for young adult readers as well as adult readers, but it does contain some violence and threat as well as suicide.

Do you need to have read The Tempest to understand Oceanus?

No. Readers have mentioned in their reviews for Oceanus that they had no prior knowledge of The Tempest, and still enjoyed the story of Oceanus. Oceanus is ‘inspired’ by The Tempest rather than simply a retelling, but readers have said that after reading Oceanus, they’ve then read the Shakespeare play and appreciated it more as a result.
