Do I Need to Read a Series in Order? The Definitive Guide

One of the most common questions about book series is whether you need to read them in order. The answer depends entirely on what kind of series it is. Here’s a guide to the different types — and specific guidance for the most popular series.

Series That Must Be Read in Order

Fantasy and romantasy series almost always require publication order. The plot develops continuously; characters change; revelations in later books only work if you’ve read the earlier ones.

• ACOTAR (Sarah J. Maas) — must read in order; Book 2 recontextualises Book 1 entirely

• Fourth Wing / Empyrean (Rebecca Yarros) — continuous plot arc; each book ends on cliffhangers

• Wheel of Time (Robert Jordan) — 14-book continuous story; absolutely must read in order
• Stormlight Archive (Brandon Sanderson) — must read in order within the series; novellas have recommended placement too

• Throne of Glass (Sarah J. Maas) — continuous arc; start at Book 1
• Inspector Gamache (Louise Penny) — continuous emotional arc; start at Still Life
• Outlander (Diana Gabaldon) — absolutely must read in order

YA dystopian series:

• Hunger Games (Suzanne Collins) — trilogy must be in order; prequels best read after the trilogy
• Divergent — continuous story; must read in order

Crime series with continuous character arcs:

• Inspector Rebus (Ian Rankin) — Rebus ages and changes; start at Knots and Crosses
• Will Trent (Karin Slaughter) — character backstory is cumulative; start at Book 1
• Maisie Dobbs (Jacqueline Winspear) — absolutely must read in order

Series You Can Start Anywhere

Standalone-in-series crime fiction is the major category where reading order often doesn’t matter. Many crime series feature recurring detectives but largely self-contained plots.

• Jack Reacher (Lee Child) — each book is self-contained; you can start anywhere, though Killing Floor is recommended first

• Alex Cross (James Patterson) — can start anywhere; each case is self-contained
• Bosch (Michael Connelly) — ideally read in order for character development, but each mystery works alone
• Sherlock Holmes (Arthur Conan Doyle) — the short stories are entirely self-contained; the novels can be read independently

Romance series where each book follows a different couple:

• Bridgerton (Julia Quinn) — each book is a different sibling’s romance; self-contained; start anywhere (though Book 1 is ideal)
• Myron Bolitar (Harlan Coben) — best in order for character continuity but each mystery largely standalone

Series With Contested Reading Orders

Some series have a genuine debate about whether to read in publication or internal chronological order.

The Witcher (Andrzej Sapkowski) — short story collections first (The Last Wish, Sword of Destiny), then novels. The short stories are not prequels in the strict sense; they’re the foundation.

Discworld (Terry Pratchett) — 41 novels in multiple sub-series. You can start almost anywhere — Guards! Guards!, Mort, or Equal Rites are all good entry points. Publication order is not necessary.

Dresden Files (Jim Butcher) — ideally read in order for character arc, but each book is a complete case. The character development makes order worthwhile.

A Quick Test

Ask three questions about any series:

1. Does the main character change significantly across books? If yes, read in order.
2. Is there an overarching plot that spans multiple books? If yes, read in order.
3. Does each book feature a completely self-contained story with the same detective/protagonist? If yes, you can probably start anywhere.

The Safest Answer

When in doubt: start at Book 1. Even in series where order isn’t strictly required, Book 1 usually introduces the world and characters most fully. Starting at the beginning never hurts; starting in the middle sometimes does.
