Before the two top books touched, their temperatures likely varied depending on their individual environments and materials. After they have been touching for a while, the temperatures of the two top books will equalize. This happens because of the principle of thermal conduction, where heat flows from the warmer object to the cooler one until they reach thermal equilibrium. So, the temperatures of the two top books will become the same after they have been in contact for some time.
