Sometimes YA fiction in the mystery/crime genre can be really dull and the characters can be very immature. Luckily, Cold Case (not to be confused with my favorite TV show on CBS of the same title) was an exception. Emotional, intense, suspenseful and riveting, this story begins as a murder mystery and soon turns out to involve government corruption, nuclear secrets, family drama and good old fashioned detective work.

Imagine a 13-year-old boy finding a dead man's body in his family's restaurant. The genre of this book is mystery. I especially liked this book because of how it leaves the reader with suspense at the end of every chapter.

13- year-old Austin "Oz" Keiller spends his Saturday mornings clean the house because of his older brother, Dave. On Saturday he notices that his older brother, Dave is not home he figures he is at his family's restaurant in Santa Fe, New Mexico. Oz leaves the house arrives

I love a good murder mystery, so when I was offered this one for review (THANK YOU) I of course said sure.

Things I Liked:
1)The relationships around Oz (the main character)--he and his brother Dave, he and his best friend Rusty, he and fellow restaurant employee Razor. They all rang true in terms of how they communicated and got along.
2)The history of Los Alamos and descriptions of Santa Fe.
3)The descriptions of how a kitchen runs. Not that I cook but still ... it made sense and seemed like it re

Thirteen-year-old Oz Keillor wants nothing more but to work at his family's restaurant and become a successful chef someday, but things take an unexpected turn when Oz finds a dead journalist in the kitchen of their restaurant early one Saturday morning, and soon discovers that his brother might have murdered the journalist over an old family vendetta involving his now dead father and some pretty nasty secrets. Shocked at his very own family for keeping such secrets and lying all these years, Oz ...more
Oz and his friend Rusty find themselves in a strange new world when Oz discovers a body in his family's restaurant, and Dave, Oz's brother, is arrested for murder. Oz's mother is in France, and the list of adults Oz can turn to is short. He and Rusty embark upon their own investigation since the police seem to think it's an open and shut case. What connection did the murdered man have with Dave, and with Oz's dad, once a scientist at Los Alamos, uncovered as a spy, and dead before Oz was born? T ...more

Imagine be a 13-yr. old boy, with a life that seems to be normal for what you know. Until you go to the family restaurant early one Saturday morning and are horrified by the sight that you see. The back door light is busted out, the back door is unlocked with no signs of forced entry, and there is such an errie feeling in your body. Then, when you turn on the lights you see something you couldn't have imagined would be there in a million years. Blood!

This book totally took me back to when I was 12 and reading my first mystery novel! Actually, I may have been younger. It was Megan's Island by Willo David Roberts. Ah, the memories. Moving on.

Poor Oz! He goes into the family restaurant to get things ready for the night and finds a dead body and a LOT of blood in the freezer. Not exactly conducive to a nice evening. Things rapidly spiral out of control when it looks like Oz's brother had the perfect motive and opportunity. The police also enligh

My thoughts:
Finding a dead body in a walk in freezer is not a good way to start the day. But things go from bad to worse when Oz's big brother and head chef is accused of murder and thrown in jail. Suddenly it's up to Oz to get to the bottom of the crime and fast because police are starting to look at him as a possible accomplice.
Cold Case is a sharp, engaging, detective mystery perfect for middle school readers, as well as older readers. Main character Oz feels like the real deal as he strugg

I liked this novel. It was very good. While it is all of these things, it is not one of my favorite mystery novels. The characters were all good. They each had their own underlying secrets and there was some twists and turns with characters that you didn't expect. I believe that the theme of this novel was it is always someone you don't expect. I thought it was one person but in the end it was someone you thought was your friend. The plot of the novel was very intricate. There was a lot of under ...more
Summary: It’s just another Saturday morning in Santa Fe when Austin “Oz” Keiller walks into his family’s restaurant to prepare for the day. He immediately notices that things are amiss in the restaurant. Perhaps it’s the fact that the door is unlocked, or the place smells like rust or bleach, or,’s the frozen dead man in the freezer!

Oz’s older brother, Dave, immediately becomes the prime suspect and is charged with murder. It’s up to Oz and his best friend, Rusty, to figure out exact

This mystery has all great ingredients: a Sante Fe setting, a family restaurant, and a boy (named Oz) who stumbles into a mystery when he finds a dead body in the restaurant's freezer. The situation worsens for Oz when his brother becomes the prime suspect. The plot is complex, with many twists and turns, as well as a subplot mystery about Oz's late father and his role in a Los Alamos lab years ago. I could not figure out who committed the crime until the very end, but I was always intrigued, as ...more

While Oz's mother is away helping her own mother who has had a stroke, it is left to Oz to figure out who killed the newspaper reporter and how his death connects to the accusations involving his father.

Despite the lackluster cover and title, I found this kid oriented mystery a better read than Grisham's "Theodore Boone, Kid Lawyer," geared to the same age range. As a relentless reader of adult mysteries, I have to adjust my expectations when reading this genre for kids and teens and not judge them against the plotting and characterization of a Ruth Rendell. This book held up the whodunit aspect for longer than most and gave a decent feel for the city of Santa Fe. There is just enough history o ...more
Nov 23, 2011 Tracey rated it liked it  ·  review of another edition
This novel is very much like Grisham's Theodore Boone:Kid Lawyer books. For an adult, solving the crime is not a tough task - the foreshadowing is laid on pretty thick. However, I can see how a young reader would enjoy the story. The protagonist is 13 years old and so I would imagine that someone of that age reading this book would enjoy how smart and brave Oz and Rusty are. I like that Rusty is a female and that she is more of the CSI brains of the operation. I find it odd that the parents are ...more

This is a great mystery book that I would recommend to anyone who love reading mysteries, suspense, or adventure books. This book is about a boy named Oz Keillor who finds a body in the walk-in freezer at his family’s restaurant. What I liked about this book is that the murderer was someone unexpected. All the characters developed a lot as well. However, there are just too many suspects. Too many characters were made just to be a suspect. In addition, the character made to be a suspect don’t mak ...more

A murder mystery set in Santa Fe, New Mexico. Young Oz Keillor finds a dead man in the kitchen of his family's restaurant. Is older brother is arrested for the crime. Oz is certain he is innocent, can he and his best friend Rusty learn the truth in time to save his brother. I enjoyed this book but felt many similarities to the Theodore Boone series and there was some predictability in the ending.

I personally enjoyed this book a lot! The author uses a curious teen as the main character,Oz, and through him and his adventures we see how far and how many barriers and limits someone will go through and break to reach the truth. Oz has been given such an image about his dad, whom he never knew and he is determined to find out the truth about his dad. S he and his friend, Rusty go throughout Santa Fe searching for clues and answers to the sudden events that had occurred. Un
It took me a really long time to get into this book, but I did end up enjoying it. Mysteries are pretty scare for young adults, and this is a pretty decent one. And a murder mystery, at that. I thought the "whodunnit" was pretty obvious, although I'm not sure teens would feel the same way. It felt very odd that Oz was so alone in the world, I guess that added to his sense of urgency in solving the crime.

I think that this a really good murder mystery I've read. You really have to think if you want to figure who did committed the crime. In this book it turns out to by someone I didn't even think it would by so it really surprised me. It really keep keep you on your toes with a bunch of action of trying to figure who did it. With two mysteries in one this is one good book.
Aug 20, 2011 Amy rated it it was ok  ·  review of another edition
A book with a murder, some mystery from the past,and a kid searching for the truth about his Dad. I found the plot a bit slow and I have a hard time with books where the bad guy (who I guessed very early on) actually sits there before killing his intended victim and explains how he did the deed. It just didn't ring true to me.

Excellent Mystery read! Likeable characters with a little history mixed in. Main characters are male and female. This story allows a young thirteen year old to take control of a situation. This will make a great book report book.

I didn't really like this book. I sort of lost interest through the middle of it. The beginning was okay. It just didn't make sense to me through out some of it. I felt like i re-read too many things. I didn't understand it at all.

This is a great adventure book for kids. It's a crime drama (CSI, THE MENTALIST, THE CLOSER, etc) for middle-grade readers. They will love it!
