Yes indeed, Eleanore M. Jewett's 1962 historical fiction middle grade novel Big John's Secret has been a both engaging and entertaining reading experience (and one that both my adult self and my inner child have very much both appreciated and enjoyed and with my inner child definitely also regretting that I did not encounter Big John's Secret as a younger reader, for Big John's Secret would most definitely have been right up my proverbial reading alley when I was a teenager and really into Mediaeval and in particularly of course British history).
And without giving away too much information (too many spoilers) regarding the specific plot and thematics of Big John's Secret (except to say that by the end of the novel, Big John has successfully completed his quest and also realises that the world is good and revenge not really something to strive for), I have to say that first and foremost and most importantly, I very much appreciate how the author, how Eleanore M. Jewett has captured a successful and authentic feeling of historical time and place, that she brings late 11th and and early 20th century England and the so-called Holy Land, the areas around Acre and Jerusalem delightfully and realistically to life (but also without too much textual violence, without too much gruesomeness and indeed even when Eleanore M. Jewett is describing the battles and warfare of the Fifth Crusade). And with said Fifth Crusade firmly in mind, I also really do find it majorly textually refreshing that in Big John’s Secret the Saracens are not generally depicted by Jewett as inherently negative, as potentially evil and horrid, but as worthy enemies who are often even depicted and shown as being considerably more forgiving and less one-sidedly “anti” than the Crusaders often deport themselves towards and against their Muslim adversaries (it certainly makes me smile and it also makes me appreciate that while the violence that generally and consistently inhabited the Middle Ages is not ever being denied or explained away in Big John’s Secret, there is also and happily no glorification of or of revelling in bloodshed and carnage for Eleanore M. Jewett).
However, as an adult reader, there are two minor issues with Eleanore M. Jewett’s writing for Big John’s Secret which does tend to bother me a trifle as an adult reader (albeit I also do think that I would not necessarily have even been aware of these bones of narrational contention if I had read Big John’s Secret when younger, when a teenaged reader). For one, there is in my humble opinion a few potential problems with pacing, such as for example the start and the ending of Big John’s Secret rather feeling a trifle too rushed, but with the middle part of Big John’s Secret getting just a bit bogged down in minutiae and kind of textually slowing down so much so as to almost become somewhat dragging and tedious. And for two, while for middle grade and young teenaged readers, the lack of character depth encountered in Big John’s Secret (where all of the featured persons both primary and secondary do not really present all that much nuance and are generally rather on the surface) is pretty much insignificant, my adult self definitely and certainly rather misses more more developed and emotionally deep characters (but yes, that for reading by the so-called intended audience, Big John’s Secret rates with four stars and is highly and warmly recommended).
