TWO RHYMING RIDDLES

1)
Against my grip
You may resist;
But in the end
You will desist.

Love or hate me,
I'm undeterred;
In the end
I'll have my third.

2)
My author's name's uncertain,
Yet my title is the same;
I contain random writing,
Yet order is my game.
Read me one day,
My pages are bare;
Try another day,
And the words will be there.
