Things We Left Behind summary

INTRODUCTION: WHEN YOUR SOULMATE IS YOUR WORST ENEMY

“There would be no new stories now. My sweet, brilliant dad was gone.” My heart cracked reading Sloane Walton’s grief in Chapter 1.

But nothing prepared me for the atomic bomb Lucy Score drops next: Sloane’s sworn enemy, cold billionaire Lucian Rollins, might be the only man who truly understands her pain. Let’s unpack this emotional grenade in my Things We Left Behind Summary.

This finale to the Knockemout series isn’t just spicy romance—it’s a raw exploration of trauma, family secrets, and whether love can rewrite a past drowning in betrayal.

WHAT’S THINGS WE LEFT BEHIND ABOUT?

Picture this: Sloane Walton, Knockemout’s fiery head librarian, is drowning in grief after her dad Simon’s death. At his funeral, she locks eyes with Lucian Rollins—her childhood neighbor turned billionaire “Lucifer.” They’ve hated each other for 22 years over a shattering betrayal. Sloane sees only ice in his eyes. Lucian sees the girl he secretly loved since they were kids.

As Sloane numbly sorts library donations and dodges her mom’s tears, she discovers her dad’s last mission: freeing Mary Louise Upshaw, a woman jailed for 25 years protecting her son. Sloane dives into the case with friends Naomi and Lina, unaware Lucian’s already pulling strings behind the scenes.

Cue the chaos:

  • Disastrous dating app fails (think a guy who brings his mom).

  • Lucian’s silent acts of care (dropping burritos at her door).

  • A library arson attack tied to a prison corruption ring.

  • Sloane’s wrist scar—a haunting reminder of how she once saved Lucian.

Forced together by danger and Mary Louise’s case, their explosive chemistry ignites. Sloane learns Lucian’s “ruthless” facade hides childhood abuse scars. Lucian realizes Sloane’s anger masks heartbreak he caused. But when a crime boss targets them, their fake hatred crumbles. Truths explode. Bodies collide. And a love buried for decades fights its way into the light.

✍️ ABOUT LUCY SCORE: QUEEN OF HEARTBREAKER HEROES

Things We Left Behind summary
Author’s image source: thebookseller.com

Lucy Score—#1 NYT bestseller and master of making us cry into our wine—grew up “at a dinner table for reading.” A journalism grad, she crafts kick-ass heroines and heartbreaker heroes who banter like enemies and love like soulmates. She lives in Pennsylvania with her husband (“Mr. Lucy”) and chaos-cat Cleo.

Her style? Addictive. Think:

  • Dialogue that snaps (Sloane: ”I’d rather lick a dumpster.” Lucian: ”Noted.”)

  • Emotions that wreck you (grief, trauma, and that cemetery confession scene ).

  • Spice that sizzles (yes, it’s open-door—and gloriously emotional).

Knockemout is her crown jewel, but explore her Benevolence and Riley Thorn series for more small-town magic.

❓ FAQ

Q1: Is Things We Left Behind spicy?

A: YES! ️️️️ Lucy Score delivers emotionally charged, open-door scenes that advance the plot (and melt your Kindle).

Q2: What’s the Knockemout series about?

A: Small-town chaos, found family, and explosive romances. Book 1: Naomi/Knox. Book 2: Nash/Lina. Book 3: Sloane/Lucian’s epic hate-to-love.

Q3: What’s the core story here?

A: Librarian Sloane and billionaire Lucian battle 22 years of hate, grief, and a dangerous corruption plot—while discovering hidden love.

Q4: Can I read this as a standalone?

A: Possible, but not ideal. You’ll miss context on the friend group. Start with Book 1 (Things We Never Got Over) for max impact.

Q5: Does Lucian have trauma?

A: Deeply. Childhood abuse makes him believe he’s “damaged.” His journey to self-worth is POWERFUL.

Q6: Is there a happy ending?

A: YES! A swoon-worthy epilogue with a Christmas wedding, babies, and cherry blossoms.

Q7: What’s the significance of the library?

A: Sloane’s sanctuary. Its arson attack symbolizes her world shattering—and rebirth.

Q8: How does Mary Louise’s case fit in?

A: Her unjust imprisonment connects to a crime boss. Solving it forces Sloane/Lucian to work together—and face their past.

Q9: Is the banter as good as Book 1?

A: BETTER. Sloane’s “dumpster” insults vs. Lucian’s icy comebacks are LEGENDARY.

Q10: Should I brace for tears?

A: Absolutely. Grief, trauma confessions, and Lucian’s love speech will wreck you (in the best way).


CONCLUSION: WHY THIS BOOK STAYS WITH YOU

Let’s be real: I finished Things We Left Behind with puffy eyes and a happy heartache. Lucy Score doesn’t just write romance—she writes emotional earthquakes.

Sloane and Lucian’s journey from venomous hatred to vulnerable, all-consuming love is a masterclass in character depth. The library fire, Lucian’s cemetery speech, the cherry blossoms… these moments tattooed themselves on my soul.

Key takeaway? Healing isn’t pretty—it’s burritos at midnight, ugly crying, and choosing love when every scar screams run. If you crave romance with grit, humor, and a found family that feels like home, this is your next obsession. Knockemout isn’t just a town—it’s a state of heart.
