Little Adventurer: Call of the Gods (World Of Axdoria Book 1) by John V. Alexandrov

Even in Magicor, spectacular city of wizards and magical creatures hidden among the clouds, Orto is unique. He is the result of a one-of-a-kind pairing when Aporton, a prominent wizard, is seduced by the song of a beautiful nymph. Their passion is fleeting but the results are not as one morning a strange boy with haunting green eyes is delivered in a basket to the wizard’s doorstep. Aporton, who has never fancied himself a father, takes the boy in and everything changes.
