t   h  eb
  ee   r  i
   s   o  k

Use simple substitution code (letters to digits) to get a 3x3 magic square.

Rem: eb=10*e+b

Since the problem is dealing with digits then "ee" must be no lager than 11.

Take the magic square
8 1 6
3 5 7
4 9 2
 and rotate it clockwise:
4 3 8
9 5 1
2 7 6

Now add 2 to each value:
 6  5 10
11 7 3
 4 9  8


(I note Charlie has brought in leading zeroes which do not appear to be ruled out by the problem text).
