There is a difference between reading on a couch and actually reading. One is what happens when you have twenty minutes and nothing better to do. The other is a deliberate act - an evening constructed around the book in your hands. The second one is better, and most of it comes down to how you set up the room before you open the page.
Here is how to set reading atmosphere candles and everything else that goes around them.
Start With Scent
Light the candle at least ten minutes before you sit down. This sounds like a small detail. It is not.
A candle that has just been lit is still establishing itself - the wax pool is shallow, the throw is weak, the fragrance is only at the wick. After ten minutes, the pool has opened, the scent has dispersed through the room, and the atmosphere has already changed. You sit down into something built.
For a reading evening, the scents that work best are the ones that recede into the room. Warm wood, vanilla, amber - these build and then settle behind you. They become the background. Sharper notes (citrus, fresh florals, clean linen) stay in the foreground and compete for attention. You do not want to notice the candle. You want to notice the book.
The Reading Room and Slow Hours collections are built for exactly this - background candles in the best sense.

Then the Light
Reading needs more light than atmosphere typically wants. The solution is layered lighting, not overhead lighting. A floor lamp behind and to the side of your reading chair, a small table lamp within reach, and the candle. The candle contributes warmth and movement to the visual field, not lux.
Get the light warm. Cool LED light activates alertness in a way that works against long reading sessions. A bulb below 3000K, in a warm shade rather than a white one, changes how the room feels and how long you actually stay in it.
The Chair
If you have a specific reading chair - a corner it lives in, a lamp positioned for it - use it only for reading. This is not aesthetics advice. It is habit advice. The brain learns to associate places with states. A chair that you read in consistently starts to function as a cue, the way the candle's scent eventually will.
If you do not have a designated chair, identify one and stop using it for anything else for a few weeks.
The Drink
Having something to drink while you read gives your hands something to do in the moments you are not turning pages. Tea works better than coffee for evening reading (lower caffeine, longer evenings, compatible with the atmosphere). Something warm rather than cold. Something you made with some intention rather than just grabbed.
Putting the Ritual Together
The sequence is: candle on, wait ten minutes. Lamp on, overheads off. Drink made. Book and nothing else. Do not bring your phone into the reading chair. The atmosphere you are building is an argument against distraction - make the argument fully.
The Slow Hours collection was designed for evenings like this. Browse the Reading Room collection for scents built specifically around the experience of reading - old books, warm wood, amber, and the quiet particular to a room where someone is being very still with a very good book.
