Our family is always reading together *quality* fantasy literature.
To us the most under-praised and under-publicized fantasy trilogy of all is "The Noble Warriors," in three volumes-- Seeker: Book One of the Noble Warriors, Jango: Book Two of the Noble Warriors, and Noman: Book Three of the Noble Warriors.
It's about two teen boys (Seeker and Wildman) and one teen girl, (Morning Star), and it soars, with evocativeness and compassion and even tenderness, into their fantasy and magical civilization's politics, hypocrisy, authoritarianism, homeless underclass, gangs, wars, and above all these sensitive teen's heroism and their spirituality -- their engagement with each other, fraudulent cults, barbarous religion (including human sacrifice), peaceful (and magical) monasticism, and their true spiritual seeking.
It touches seamlessly and coherently on so many deftly interwoven themes. It is absolutely action-packed entertaining, audaciously intelligent, adventurous, deeply reflective, much too-little known, and a simply stunning achievement.
