Our Review

The Setup

On the day of his Proving, apprentice summoner Samuel Eamon discovers something deeply inconvenient about his magic: everything he tries to summon turns into a succubus. Every single thing. It is an absurd and immediately compelling premise that sets the tone for the entire book.

To make matters more complicated, he gets paired with Aurora, a gorgeous former classmate who bullied him relentlessly at the academy and has since become a nun. The two must journey together to find a Runescribe who can explain Samuel’s peculiar abilities. Along the way, he juggles nightly obligations to his growing collection of succubi, fights goblins and monsters, and navigates the political conspiracies of a world where summoners wield serious power.

What Works

The succubi are the best part of this book, and that is exactly what you want from a succubus harem. Each one has a distinct personality that goes well beyond being a sex object with wings and horns. Knightley clearly understands that monster girl harem fiction lives or dies on whether the girls feel like actual characters, and he delivers on that front. The variety among the succubi keeps interactions fresh and gives each one a unique dynamic with Samuel.

The enemies-to-lovers arc between Samuel and Aurora is genuinely compelling. Watching her transition from antagonist to grudging ally to something more is one of the better slow-burn developments in recent harem fiction. It gives the story emotional stakes that pure wish-fulfillment often lacks. Their bickering has real tension behind it, not just sitcom-level misunderstandings.

The dual narration in the audiobook version brings the characters to life effectively, with distinct voices that help differentiate the large cast.

What Doesn’t

Samuel himself is the most divisive element. He occupies an awkward space between bumbling and know-it-all that some readers find endearing and others find grating. If you need your harem MC to project confidence and competence from the start, Samuel’s early chapters will test your patience. He grows into his role, but the journey there involves a lot of moments where you want to grab him by the shoulders and tell him to stop being such a pushover.

The world-building, surprisingly for Knightley, is thin in places. How the magic system actually works remains frustratingly vague. For a story built around summoning, you would expect clearer rules about what the system can and cannot do. That lack of structure makes some plot developments feel arbitrary rather than earned.

The Heat

Despite the succubus premise practically screaming explicit content, the spice lands at a moderate 3. The buildup is suggestive and consistent, but the actual intimate scenes feel somewhat restrained given the setup. Multiple readers note a disconnect between the erotic tension the story generates and the payoff when scenes actually happen. If you are picking this up specifically for the succubus harem heat, adjust your expectations: this is more fantasy adventure with romantic elements than dedicated erotica.

Bottom Line

Succubus Summoner is worth reading for the character work, especially Aurora’s arc and the distinct succubi personalities. The premise is a blast, and Knightley’s humor keeps the journey entertaining even when the pacing slows. Just know going in that the MC is an acquired taste and the heat level does not quite match what the word “succubus” promises. If you enjoy succubus harem books for the monster girl fantasy and character dynamics more than pure spice, this is a strong pick on Kindle Unlimited.
