"...a beginning reader mystery with definite child appeal...The crisp and sometime sarcastic dialogue and unintentional misbehavior of the boys are so typical."
- CM Magazine
"This story has a very straightforward, simple plot, with good use of limited vocabulary. True to the series title, First Flight, most readers just beginning to tackle a full chapter book will find this one relatively easy to read."
"...an action-packed adventure that's also a perfect transition book for young readers who are ready to move from picture books to chapter books...Jennings seems to have a strong sense of how kids' minds work and what interests them, and that comes through in her clear writing style and fast-paced action. Mardon's illustrations add to that sense of action and provide excellent visual clues for readers just moving up to the chapter-book level. We look forward to seeing more of Sam and Simon."
