Do you wish to really understand Eichah?
Do you wish to be able to truly experience the pain of the Churban the way Yirmiyahu Hanavi expected when he wrote Eichah?
Do you find Tishah B'Av a day which is too long and boring, God forbid?
Now you have a book that can help you with relating to Tishah B'Av like you always really hoped to, and through mourning the destruction you will merit the eventual redemption.
