Tamsyn Muir

Tamsyn Muir, a Kiwi, has spent most of her life living in Howick, New Zealand, spending time in Waiuku and central Wellington. She lives and teaches in Oxford, in the United Kingdom. She used to believe that being a New Zealander had not affected her writing all that much, either in setting or flavor.

The best place to start is The Locked Tomb series, the earliest of Tamsyn Muir's multi-book series: it opens with Gideon the Ninth (2019) and runs to 5 books across 2019–2023, ending with The Unwanted Guest (2023). Tamsyn Muir's other series stand alone, so they can be read in any order.

Tamsyn Muir has 49 books catalogued in this guide, published between 2009 and 2026. 31 of them belong to 3 named series — the largest being the Into Shadow series with 7 books — and 18 are standalone titles, collections or anthologies.

Read each series in publication order — the numbered entries in each series follow the year each book first appeared. Tamsyn Muir's series do not depend on one another, so they can be started in any order; by start date they are The Locked Tomb (2019–2023, 5 books) and Into Shadow (2022, 7 books).

This guide splits Tamsyn Muir's 49 books into 3 named series and 18 titles that stand alone or appear only in collections: Into Shadow (7 books, 2022); The Locked Tomb (5 books, 2019–2023); Best Horror of the Year (19 books, 2009–2026).
