Mark Hart examines the living of faith in everyday life and questions concerned and answers them in short texts.
I think the book is aimed to young readers, teenagers and above (given certain shortness and simplicity - which I assume are intentional for this purpose), but even more mature reader can stop and examine his faith life both in its basics, so to say, and in more specific aspects of their own situations.
This book might be appealing to male readers, I suppose, as Mark Hart has this dry, pointed humour I can find in many male friends of mine.
