This is another fine addition to Squadron Signal's line of In Action books and is sure to complement your library. The book takes you to Jack Northrop's response to the Army Air Corps‘ call for a secret purpose-built night fighter, and follows it from the drafting table to wind tunnel testing, factory manufacturing, test flying, and finally to combat. The book also covers all production variants and prototypes.

The book comes in either softcover or hardback; it's 80 pages that contain 30 vintage color and 164 black & white photographs plus 4 color plate profiles and a dozen detailed line drawings. It's well written, in-depth, and laid out keeping the modeler in mind. The photos alone are a wealth of information.

With the old 1/48 Monogram kit looking better all the time, the newer P-61 lines in 1/48 from Great Wall Hobby, and the larger 1/32 Hobby Boss Kits, this book will surely come in handy. I highly recommend it.

My Thanks to Squadron Signal, Squadron MMD, and IPMS-USA for the review copy and review opportunity.
