"Krishna Book" A Summary Study of Srila Vyasadeva's Srimad-Bhagavatam, Tenth Canto by His Divine Grace A.C Bhaktivedanta Swami Srila Prabhupada 

It is a beautiful compilation of Authentic Divine Sweet Pastimes of Lord Krishna, with beautiful 132 colour art plates depicting his authentic divine sweet pastimes, including his appearance, his sweet childhood pastimes, playing with cowherd boys while grazing cows, killing powerful demons inexplicably, luring Vrindavan residents, performing the Rasa dance with the gopis, blessing demigods, acting as the king of Dwarka, and displaying his opulence as the Supreme Personality of Godhead.

Krishna Himself says in Bhagavad Gita 4.9 - 

One who knows the transcendental nature of My appearance and activities does not, upon leaving the body, take his birth again in this material world, but attains My eternal abode, O Arjuna.

Kṛṣṇa is killing so many demons, Kṛṣṇa is dancing with gopīs, Kṛṣṇa is playing with His cowherd boys, Kṛṣṇa is going there, this is līlā, smaraṇam. The Kṛṣṇa book reading means remembering all these activities of Kṛṣṇa. Simply go on reading Kṛṣṇa book, repeat it, you are in the perfect stage of transcendental position.

~ Srila Prabhupada Lecture on SB 7.7.28, 32-35 -- Mombassa, September 11, 1971

 If you simply read Kṛṣṇa book, although it looks like story, then you become delivered from these clutches of repetition of birth and death.It is so nice. Because you will understand Kṛṣṇa, what is Kṛṣṇa, and here it is said, janma karma ca me divyaṁ ye jānāti tattvataḥ (BG 4.9). It is explained. The people who are reading Kṛṣṇa book very seriously, and tries to understand Kṛṣṇa, he will understand. Kṛṣṇa is very kind. As soon as he begins reading Kṛṣṇa book with a little faith and adherence, Kṛṣṇa will be very much pleased
