an outside perspective
Hi,
Is it ok to use a phrase " an outside perspective". Is it ok to use it in the following context;
"In this regard, there are a whole bunch of authors I would strongly recommend everybody to get familiar with. From Nikolay Berdyaev, to Kate Fox and James Billlington whose book called «The Icon and the Axe» made a lot of buzz in its time. This book is nothing but an outside perspective on russian culture."
Thank you very much for help.
