Poderia ser " Flamers " de Nicholas Fisk? (também conhecido como " Escapar do Splatterbang ")? Para obter emprestado de um resposta anterior (negrito meu):
The novel was set on Splatterbang, a planet with an atmosphere unbreathable to humans, a dying ecosystem, and some very dangerous native life forms: the titular "Flamers", which resembled living fireballs that were attracted to and consumed metal. The boy and the girl were named Mykl and Amina respectively. The base in which Mykl takes refuge after being marooned on Splatterbang is operated by an AI named "Ego". After learning Mykl's name, Ego says that it's a very old name that used to be spelled "Michael". The scene with the image of the girl on the monitor occurs in the base, before he meets Amina. Ego says that the image is old data that shouldn't be there, but offers to give her a voice and personality as a companion for Mykl. The first attempt to rescue Mykl and Amina failed because the cable used to lower the rescue pod was made of metal and was attacked and consumed by the Flamers. Another detail that I remember is that spacesuits were usually equipped with a device called a "strong right arm" that provided enhanced strength; in one scene, Mykl uses it to break a mechanical lock with his thumb.
