Below, every title listed includes a single, original one-line “what it is” note, so you can choose quickly without digging for blurbs.

Alliance series (read in order)

Tightly connected world; later books land harder once you know the power dynamics and the circle around them.

1. Nero (2023): A dangerous, possessive man decides a woman is his, and starts rearranging her life to prove it.
2. King (2023): A man with a brutal reputation meets the one person who doesn’t flinch, and he takes that personally.
3. Dom (2023): A control-obsessed fixer collides with a woman who has her own rules, and neither side backs down.
4. Hans (2023): A quiet, watchful man finally steps out of the shadows, and his version of “courting” is intense.

---

Sin series (read in order)

Rom-com bite, escalating intimacy, and recurring faces that make more sense in sequence.

1. Mr. Sin (2021): A charm-heavy setup turns serious when the “fun idea” starts rewriting real feelings.
2. Sin Too (2021): A second round of temptation tests whether boundaries are real, or just something to negotiate.
3. Miss Sin (2021): The messiest emotions surface last, forcing a couple to choose honesty over image.

---

Sleet series (read in order)

Same series lane, different couples; best in order for cameos and the “who already knows what” factor.

1. Sleet Kitten (2021): A bold attraction starts as a game until it stops feeling optional.
2. Sleet Sugar (2021): Sweet on the surface, complicated underneath, this romance turns on trust and timing.
3. Sleet Banshee (2021): A loud, chaotic spark hides a surprisingly tender core once the walls crack.
4. Sleet Princess (2024): A later return to the world that pays off best after you’ve met the earlier cast.

---

Darling series (read in order)

A compact duet, quick to finish, easier to enjoy if read back-to-back.

1. Smoky Darling (2022): A smoky, magnetic connection turns into a high-stakes emotional claim neither expected.
2. Latte Darling (2022): Softer vibes, sharper feelings, this one leans into comfort, devotion, and staying power.

---

Bite series holiday novellas (read in order)

Short, seasonal, high-heat bites; order keeps the “in-jokes” and familiar beats from feeling random.

1. Second Bite (2022): A quick, spicy romance that plays with “we shouldn’t” until “we did” becomes the point.
2. Snowed in Bite (2024): Weather traps two people together long enough for attraction to become a decision.
3. New Year’s Bite (2024): A fresh-start setup turns into a not-so-casual “claim” as the year flips over.

Collection note (optional):

• Baby Cakes: The Complete Bite Series (collection): A bundle edition meant for convenience, not a separate story.

---

Love Letters series (best read with the prequel first)

This shelf leans into letters, history, and emotional backlog. The prequel is short but clarifies the “then vs now” contrast.

0. Tackled in the Stacks: A Love Letters Prequel (2026 listing on the author’s series page): A college-era spark forms in close quarters, setting up the adult reunion tone.
1. Love, Utley (2024): A decades-later collision forces two people to deal with what one week together started.
2. Dear Rosie, (2024): Childhood friendship resurfaces in adulthood, and recognition changes everything mid-attraction.

---

Mountain Men series (read in order)

A continuous setting with a “mountain community” feel; each book is its own couple, but the world sticks around.

1. Mountain Boss (2024): A desperate fresh start meets a grumpy man who hates disruption, and wants her anyway.
2. Mountain Daddy (2024): A one-night escape backfires when the man turns out to be permanently off-limits.
3. Mountain Grump (2026): A marriage-of-convenience scramble turns real when feelings stop pretending to be practical.

---

Bonded Souls (separate continuity) (start here when it releases)

This is presented as its own alternate “Tilly-verse” lane, separate from the rest of the shelves.

1. Volik (2026): A new world opens with fated-mates energy and a paranormal edge aimed at starting fresh.

One clean “starter stack” that covers her range

1. Nero (for the Alliance tone)
2. Mr. Sin (for lighter rom-com bite)
3. Second Bite (for short-form spice)
4. Mountain Boss (for setting-driven romance)
5. Tackled in the Stacks → Love, Utley (for letters + second-chance weight)
