Book Description

Math teacher extraordinaire and inveterate busybody, Bonnie Pinkwater is at it again. When she and her Wiccan sidekick Rhiannon Griffith are out hiking and find the body of Bonnie‘s boss, Vice Principal Clarence Murphy, their day takes a decided turn for the worse. But when that same body disappears then reappears seated at his desk, amid the wreckage in a tornado-ravaged high school, Bonnie proclaims things downright weird and decides to nose around. What show up are killer motorcyclists, suspicious preachers, tyrannical dwarves, high-stakes poker games, land-grabbing CEOs, and a damaged math genius desperately needing her help. As Bonnie and Rhiannon sort through a rising body count, Bonnie comes to a disturbing conclusion. Whoever is murdering the good citizens of East Plains, Colorado, has decided to eliminate one meddlesome math teacher.

5.0 out of 5 stars Excellent characters, well-crafted story April 4, 2012
Format:Kindle Edition
Radical Equations is an excellent read: well-paced, finely written, and filled with enjoyable characters in a realistic small-town setting. Although it is the fourth mystery featuring high school math teacher Bonnie Pinkwater, readers new to the series (as I was) will not feel at a disadvantage, as the main action is independent of prior storylines.

Bonnie has the brains and irrepressible nosiness to be a good amateur sleuth, and whacky Wiccan BFF Rhiannon is an excellent sidekick. I also especially enjoyed Bonnie's scenes with former-student turned cop, Byron Hickman. The eastern Colorado setting is convincingly presented. The tornado scene early in the book is absolutely smashing (pun intended), and had me clicking "next page" as fast as I could read.

Bonnie's interactions with school district administrators and community oddballs ring true. It was fun to watch Bonnie struggle to keep her naturally sharp tongue and sense of humor from getting her fired. The plot is nicely tangled, and kept me guessing until the end.

I received a complimentary Kindle edition of this book in exchange for an unbiased review, and am eager to read the other books in this fun series.

4.0 out of 5 stars I enjoyed Missus Pinkwater March 26, 2012
Format:Kindle Edition
Even though this is the fourth in a series that I'm unfamiliar with, I had no trouble jumping right in! I loved the small-town characters and cozy feel of this book. Bonnie Pinkwater, math teacher and amateur sleuth, was endearing and sometimes funny. She comes across as real person with only her human abilities, not a superhero ninja crimesolving savant. She's smart and compassionat--and a smart aleck :) I loved her attitude and I'll be catching up on the preceding books, and on the lookout for more adventures.

3.0 out of 5 stars Pinkwater mystery March 24, 2012
By marglyn
Format:Kindle Edition
A complimentary copy of this book was sent to me on my kindle for reviewing.
I have not read any Bonnie Pinkwater mysteries before now. A female character who is a busybody and a teacher involved in solving murder with her friend who is a witch. We are not told much about her history, you are expected to know this already from the first book I assume. I would have liked a bit more information at the beginning of the book.
It is well written and keeps you guessing as to who is the murderer until near the end. This is a book that someone would take on holiday with them to read on the beach.

5.0 out of 5 stars Didn't see that one comin' March 22, 2012
Format:Kindle Edition
I really enjoyed this book. The characters were well written and easy to like. Dialog is smooth and conversations are like in real life (it bugs me when conversations are stilted by authors using proper english since people don't really talk that way). Lots going on but easy to follow. I didn't see the ending coming and I love when that happens.

I received a complimentary copy of this book in order to review it.

5.0 out of 5 stars radical equations February 5, 2012
Format:Kindle Edition
Once again Misses Pinkwater is sticking her nose where it doesn't belong. The algebra teacher from from east plains high school has come across the dead body of her assistant principal not once but twice in one day. Not only is she dealing with her confusing lovelife, but she also has to deal with a tornado, her arch nemisis superintendant Devine, and bodies turning up all over the small town of East Plains. With the help of her witchy friend Rhiannan and her ex-pupil turned cop Byron Hickman, Misses Pinkwater goes on an adventure that will keep you guessing to the last chapter. Radical Equations is a wonderful book that you will not want to put down, and might just learn a little math.

4.0 out of 5 stars Fast-paced and a little goofy February 4, 2012
Format:Kindle Edition
In short: Math teacher Bonnie Pinkwater gets caught in a murder mystery centered around a tornado and a dead vice-principal. Despite being the fourth book in a series, new readers shouldn't have problems jumping in.

This is a good, solid mystery. I hesitate to call it a cozy, but I suppose it is: an older woman/amateur sleuth solves mysteries in a small town. To me, Bonnie's character always carries out a satisfying rebellion against the educational bureaucracy as embodied by Principal Divine, sometimes getting her licks in, sometimes having to grovel in order to keep her job and to defend her students. I have a soft spot for characters who defend kids without belittling them, and Bonnie hits the spot. Fast-paced, realistic, and a little goofy, a good put-your-feet-up and enjoy-the-small-victories kind of book.
