Although Stan Lee and Steve Ditko created everyone's favourite web-slinger that will forever be as popular as Batman and Superman, there was another Marvel creation under their collaboration that ware more mature and leans more toward the supernatural and the sci-fi origins of most of Marvel's back catalogue. Although Doctor Strange has his own movie that was hugely successful, his adventures were always more psychedelic than the typical superhero spectacle, including this graphic novel that is a favourite towards the Strange enthusiasts.
As part of the Marvel Graphic Novel line published from 1982 to 1993, Doctor Strange returns to the Ancient One's Himalayan home to pay respect to his departed master, and discovers that his mentor has left one final gift, in the shape of a mysterious box. Instead of facing a villain like Baron Mordo or Dormammu, Into Shamballa is really a journey of self-discovery for the eponymous doctor who, despite his title of "Master of the Mystic Arts", he is still wrestling with his inner demons, as established when his first instinct after wasting many hours trying to dissect the Ancient One's box is to simply destroy it, which immediately plunges him to some place otherworldly.
Marvel is all about flawed heroes and Stephen Strange is no exception as he was an egotistical surgeon before a car accident permanently damaged his hands. What we get from this story that has a great narration by J. M. DeMatteis, Strange may not have rid himself of his ego and feels a sense of unfinished business with his departed master. Under the writing style of a prose novel, DeMatteis goes in depth to how the Doctor ticks and no matter how outlandish the story goes, Strange as a protagonist grounds it all.
With a lengthy career as an inker, co-writer Dan Green provided the watercolour illustrations, showcasing his stunning depictions of the numerous locations from our world to the other dimensions. For a book that is word-heavy, there are plenty of pages in which it’s just the art, that is very close to Alex Ross illustrating a Doctor Strange story. Honestly, given that it was published in 1986 as well as the history of that character, you can see how Stan Lee and Steve Ditko's creation was a big influence towards the likes of Neil Gaiman's The Sandman.
Granted, this is no longer in publication (and there are diehard fans that are screaming for a rerelease), if you can track down Doctor Strange: Into Shamballa by J. M. DeMatteis and Dan Green, it is worth your time as this is a truly magical labyrinthine story that brings out the best of the Sorcerer Supreme.
