The Lily Sparrow Chronicles

Follow the adventures of Lily Sparrow, a fifteen-year-old math and logic lover, who discovers she's really the long-lost princess of a fairy tale kingdom accessible through her bathtub.

Book 1

The Cinderella Theorem

Fairy tales are naturally non-mathematical. That is a fact, and fifteen-year-old Lily Sparrow loves factual, mathematical logic.

So when her mother confesses that Lily's deceased father is (a) not dead, (b) coming to dinner, and (c) the ruler of a fairy tale kingdom accessible through the upstairs bathtub, Lily clings to her math to help her make sense of this new double life. (1 life in the real world + 1 life in the fairy tale world = a double life).

Even though it's not mathematical, Lily finds herself being pulled into a mystery involving an unhappy Cinderella, a greasy sycophant called Levi, and a slew of vanishing fairy tale characters. Racing against the clock, with a sound mathematical plan, can Lily save her fairy tale friends before they vanish forever?

Book 2

Calculating Christmas

A month after Lily and Calo rescued the characters from Cinderella and The Candlemaker's Daughter, they've been assigned to a new case. Santa's rebellious daughter, Carole, has had enough of her family and needs a change. And if that change isn't handled carefully, it could wind up derailing Christmas for everyone--a fact that will equal lots of unhappy citizens potentially vanishing. So no pressure for Lily, right? Wrong.

In addition, Lily is dealing with the ever-increasing demands of her double life, leaving her little time for her beloved math. Multiply that by the fact that she can't seem to please her parent, her friend, Corrie, is mad at her, and her relationship status with Calo is unsolvable, and you're left with a pretty stressed out Lily.

Will she and Calo manage to save Christmas? Will Lily find a way to be the Princess the kingdom expects? And how will things turn out with Carole, who is openly naughty in front of Santa Claus?

Book 3

The Sherwood Proof

Lily Sparrow has finally created an equation for being a good princess. Things are adding up and making sense, and she’s even growing a measurable amount more excited about her future. But unexpected variables keep being tossed into her equation:

  1. Carole Claus is facing her first hurdle as Santa. She needs Lily’s help.

  2. Lily’s half-birthday--an important Smythian tradition--is coming up, requiring her to find time to prepare for it.

  3. Her algebra teacher has an unusual (and stressful plan) for Lily.

  4. Lily remains convinced that her mom is hiding something from her.

  5. The investigation into the traitor is an on-going source of stress and tension at work for Lily and Calo.

  6. Oh, and Calo’s still betrothed to Su’Sauna, making life difficult and confusing all around.

Will Lily be able to place these variables securely in her equation? Will the Sparrow family find a way to convince their critics they are good for the Kingdom? Or will everything fall apart--subtracting all the good will Lily has already earned from her citizens?
