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.
