Just watched the "Miss Peregrine home for peculiar children" and vaguely remember that I read a sci-fi novel many years ago with a similar setup - a boy finds a group of children with special abilities (lead by a man whose talent is to "glue" the group).
There was a child who can teleport himself (but not his clothes :)) so he teleports himself to a store at night to get some food for the group.
There was a girl who can move other things (e.g. in the first night the the protagonist went outside to pee and afterwards they told him he should not - the girl can just empty his bladder just by her mind. Etc...
I remember the boy ends-up the new "leader" of the group because the old "leader" steps-down and he tells the boy that he also has the talent of "gluing" the group together.
Could you help to identify?
Thanks a lot in advance!
