I've had Phoenix recommended by friends and my son seems to like it. Plus Beano, and unfortunately, Teenage Mutant Ninja Turtles. Dr Who one is monthly and good. Also if you want to try lots out, there's a day a year where various comic give away samplers for free. You've missed it now, but you can pick them up for ?1 online, eg: http://www.disposableheroes.co.uk/free-comic-book-day-2015/cat_362.html Not sure what might be suitable. Also a couple of comic books that have had good reviews: http://boingboing.net/2012/04/12/giants-beware-kids.html http://www.girlgeniusonline.com/books.php http://boingboing.net/2014/03/25/james-kochalkas-the-glorki.html http://boingboing.net/2014/11/26/strong-female-protagonist-book.html
