The authors first met around 2006 on an internet forum where they shared their stories and eventually began collaborating. Their literary career kicked off in 2012 with the free publication of their first novel, Pétalos de Papel, which was read by over 9,000 people. However, it was not until 2014 that they published Alianzas with the Everest publishing house, marking the first book of the Cuentos de la luna Llena trilogy. Due to the closure of Everest in 2015, the series was picked up by La Galera, concluding with Despedidas in 2018.

The Cuentos de la luna llena series was recognized as one of the best young adult literature readings by the cultural magazine Babelia (El País). Additionally, in 2015, Alianzas won the Templis Award for "Best Series Novel," presented by the magazine El templo de las mil puertas, which focuses on young adult literature.

In 2015, they also published one of their most well-known works, Sueños de piedra, which initiated the famous Marabilia saga, consisting of five novels, the first four of which are standalone and independent. This series has been published by the Nocturna publishing house, with which they currently continue to collaborate.

In 2019, following the publication of Antiheroes, one of their most renowned novels, Selene and Iria confirmed via Twitter that the television production company Globomedia had acquired the rights to adapt the novel for television. Their latest works include the beginning of the Olympus series, La flor y la muerte, with the next book already confirmed, El sol y la mentira, and the illustrated children's novel Alma y los siete monstruos, announced as their first work to be translated into other languages.
