Jedi Quest, tome 2 : The Way of the Apprentice

Now Anakin was fourteen. He was an able Padawan who had already proven himself on several important missions. Yet there was one thing that nagged at Obi-Wan. Anakin was liked by the other students, but he had no close friends. He was not loved.
Obi-Wan told himself that Anakin’s gifts naturally set him apart. But in his heart, he grieved for Anakin’s loneliness. He was happy for Anakins’s skill and growing command of the Force. But he whished a simple thing for Anakin. It was something he could not give his Padawan. It was not a gift he could hand over, like a well-loved river stone. He wished for a friend.
