The story is inspired by characters in J. M. Barrie's Peter Pan and is a continuation of a narrative started on The Callous Heart and The Stranger which features references to various Creeper songs and lyrics.

Creeper's debut full-length album Eternity, in Your Arms was officially announced on 2 October 2016, when the band resurfaced after an absence of just over a month during which they "wiped their social media presence, appeared to be 'kidnapped', [and] started a whole load of weird, confusing phone calls from their hometown of Southampton" as part of a publicity stunt.

[1] As part of the announcement, the band also released "Suzanne" as the first single and music video from the upcoming album, the chorus of which features the phrase "We'll die holding hands", which had been shared a number of times on the group's social media during the previous month.

[9] Supported by Milk Teeth, Puppy and Energy on the UK dates,[10] the tour also visited venues in Germany, Denmark, Norway, Sweden, Austria and France, before finishing with a show in the Netherlands on 15 April 2017.

[13] Stylistically, Eternity, in Your Arms is described by AllMusic's James Christopher Monger in his review of the album as a mix between glam rock, post-hardcore and horror punk, with comparisons drawn to the work of bands including Alkaline Trio, The Damned, Misfits and AFI.

[14] NME writer Anita Bhagwandas also notes elements of pop punk on the album, especially on lead single "Suzanne", as well as making comparisons to Tiger Army and The Cure.

[15] Clash writer Dannii Leiver also highlighted elements of pop punk on "Suzanne" and "Poison Pens", as well as "nu-emo" on "Hiding with Boys" and "acoustic country" in the latter stages of the album.

[20] Monger claims that the album demonstrates "a keen sense for the pageantry of rock & roll" and features "Meat Loaf-worthy grandeur", which he highlights as a unique quality of the record.

[24] Remfry Dedman of The Independent explained that "The narrative thread that weaves its way through The Callous Heart, The Stranger and concludes with Eternity, in Your Arms is aimed directly at a sub-culture who often grow up feeling isolated from those around them", describing it as a story based on the idea of "the desire to escape, if only for a short while, and leave all your troubles behind".

[28] AllMusic's James Christopher Monger awarded the album four out of five stars and stated that "With Eternity, in Your Arms, Creeper have truly proven themselves masters of the dark arts, as they've managed to create something as genuinely inspired as it is stylistically derivative".

[18] McLaughlin praised the band's "admirable, fearless creativity" on the record, as well as highlighting the performances of keyboardist and backing vocalist Hannah Greenwood, who he claims "almost steals the show" on the album.

[18] Writing for Clash, Dannii Leivers hailed Eternity, in Your Arms as "a complete triumph", claiming that the band's "sound has truly flourished, grown wings and soared into velvet skies".

[16] Metal Hammer writer Rob Barbour claimed that "While it's certainly no genrebusting reinvention, this record is still a stunning achievement, packed from start to finish with kaiju-sized choruses and without a single note out of place".

[31] The Metal Hammer writer also questioned the inclusion of "Misery", which had been previously featured on The Stranger EP in 2016, although he conceded that "it would be churlish to pretend [it doesn't] make sense in the context of the album, or in any way ruin its masterful pacing".
