The Thrawn Trilogy by far. Those were my first and no other books, period, come close.
Next would be the Thrawn Duology, followed closely by the X-Wing books and I, Jedi.
Peace is but a shadow of death,
Desperate to forget its painful past.
And though we hope for promising years,
After shedding a thousand tears,
Yesterday's sorrow constantly nears.
Unless a grain of wheat falls to the ground and dies it remains alone.
